the four mouse ATE1 isoforms have different, partially overlapping substrate specificity toward their N-terminal target sites, detailed overview. The four mouse ATE1 isoforms show prominent and consistent differences in target site specificity, both at the N-terminus and the side chain sites. At the N-terminal sites, only three of the four ATE1 isoforms (ATE1-1, 2, and 3) show high preference for the peptides containing N-terminal D and E. ATE1-4 do not appear to target peptides containing N-terminal E. At the same time all four isoforms, to a various degree, show prominent reactivity with the peptides bearing N-terminal C. Even more strikingly, ATE1-1, unlike any other ATE1 isoforms, appears to be reactive with additional N-terminal sites not seen with other ATE1 isoforms, including Q and, weakly, H. Thus, it appears that N-terminal target site specificity of ATE1-1 may be broader than other ATE1 isoforms and potentially include non-canonical N-terminal residues. The four ATE1 isoforms also show different reactivity with the peptides bearing side chain target sites. In the case of ATE1-1 and ATE1-2, the signal with these peptides containing side chain target sites is substantially lower or absent compared to the peptides containing favorable N-terminal target sites. Side chain arginylation of one of these peptides with ATE1-2 in solution. It appears likely that the peptide array format is unfavorable for side chain targeting by these ATE1 isoforms. Isozyme ATE1-1 catalyzes arginylation of non-canonical residues. Identification of the arginylation-favorable sequence motif

after N-terminal Cys-sulfinic acid formation on ERF-VII peptide through plant cysteine oxidase. An ERF-VII peptide with an N-terminal Gly does not accept Arg, whereas an N-terminal Asp accepts Arg, independent of the presence of PCO1 or 4. A peptide comprising an N-terminal Cys-sulfonic acid is also shown to be a substrate for ATE1, again independent of the presence of PCO1 or 4.

plant ATEs and their evolutionary relationship with other ATEs, overview.

ATE1 expression is more prominent in the embryonic brain and spinal cord than in the heart. ATE1-null embryonic brain shows stabilized regulators of G protein signaling (RGS) proteins, defective G protein signaling, and a higher concentration of NO.

Cells treated with the Arg/N-end rule inhibitor become more sensitized to proteotoxic stress-induced cytotoxicity.

conditional knockout mice with Ate1 deletion in the nervous system driven by Nestin promoter (Nes-Ate1 mice) are weaker than wild-type mice, resulting in low postnatal survival rates, and have abnormalities in the brain that suggest defects in neuronal migration. Cultured Ate1 knockout neurons show a reduction in the neurite outgrowth and the levels of doublecortin and F-actin in the growth cones. A lack of beta-actin arginylation leads to a marked reduction in growth cone spreading, accompanied by the corresponding decrease in the actin polymer. Nes-Ate1 mice develope to full term and are born at the expected about 25% ratio, with the body weight and appearance at birth indistinguishable from their wild-type littermates. However, these newborn mice are visibly less active than wild-type, easily pushed away by their littermates during feeding and show no inclination to explore the environment within days after birth. These newborns exhibit dramatically reduced growth in the first days of postnatal life, likely due to their inability to compete for the mother's milk with wild-type littermates. Complete Ate1 knockout mice die at E12.5-E14.5 during development
malfunction
deletion of Ate1 in mice leads to embryonic lethality and impairments in multiple physiological systems, including cardiovascular development, angiogenesis, muscle contraction, and cell migration. Lack of arginylation leads to increased Alpha synuclein (alpha-syn) aggregation and causes the formation of larger pathological aggregates in neurons, accompanied by impairments in its ability to be cleared via normal degradation pathways. In the mouse brain, lack of arginylation leads to an increase in alpha-syn's insoluble fraction, accompanied by behavioral changes characteristic for neurodegenerative pathology. Lack of arginylation in the brain leads to neurodegeneration

deletion or downregulation of the ATE1 gene disrupts typical stress responses by bypassing growth arrest and suppressing cell death events in the presence of disease-related stressing factors, including oxidative, heat, and osmotic stresses, as well as the exposure to heavy metals or radiation. Conversely, in wild-type cells responding to stress, there is an increase of cellular Ate1 protein level and arginylation activity. The faster growth rates of ate1DELTA mutant yeast in stressing condition compared to wild-type is likely caused by a lack of growth arrest

knockdown of arginyltransferase ATE1 attenuates cardiac hypertrophy and fibrosis in vitro and in vivo through the TAK1-JNK1/2 pathway. The cardioprotective role of ATE1 silencing is mediated by the interruption of TAK1 activity-dependent JNK1/2 signaling pathway.

Cardiac ATE1 deficiency restores cardiac dysfunction after right renal artery ligation. Phenotype, overview

Double mutant for AtATE1 and AtATE2 (ate1.ate2) displays lost sensitivity to hormone abscisic acid and consequently uncontrolled seed germination and establishment. Arabidopsis ate1/ate2 or prt6 mutants cannot degrade ERFVII, and as a consequence show increased expression of hypoxia-responsive genes involved in fermentation and sugar consumption even under oxygen-rich conditions

metabolism
submergence-induced hypoxia in plants (e.g. flooded plants) results in stabilization of group VII ethylene response factors (ERF-VIIs), which aid survival under these adverse conditions. ERF-VII stability is controlled by the N-end rule pathway, which proposes that ERF-VII N-terminal cysteine oxidation in normoxia enables arginylation followed by proteasomal degradation. The plant cysteine oxidases (PCOs) are identified as catalysts of this oxidation. ERF-VII stabilization in hypoxia presumably arises from reduced PCO activity. PCO dioxygenase activity produces Cys-sulfinic acid at the N-terminus of an ERF-VII peptide, which then undergoes efficient arginylation by an arginyl transferase (ATE1). This provides molecular evidence of N-terminal Cys-sulfinic acid formation and arginylation by N-end rule pathway components, and a substrate of ATE1 in plants. PCOs catalyse dioxygenation of the ERF-VII peptides RAP2_2 to RAP2_11

the arginylation branch of the N-end rule pathway is a ubiquitin-mediated proteolytic system in which post-translational conjugation of Arg by ATE1-encoded Arg-tRNA-protein transferase to N-terminal Asp, Glu, or oxidized Cys residues generates essential degradation signals
metabolism
the arginylation branch of the N-end rule pathway positively regulates cellular autophagic flux and clearance of proteotoxic proteins. In the Arg/N-end rule pathway, a main process, that generates a primary destabilizing residue, is the posttranslational conjugation of Arg to pro-N-degrons such as Asp, Glu, and oxidized Cys. This conjugation is solely mediated by ATE1-encoded Arg-tRNA-protein transferase. Arg/N-end rule pathway-dependent degradation of Arg-HSPA5 is a critical regulatory step for autophagosome maturation.

In the Arg/N-end rule pathway, a main process, that generates a primary destabilizing residue, is the posttranslational conjugation of Arg to pro-N-degrons such as Asp, Glu, and oxidized Cys. This conjugation is solely mediated by ATE1-encoded Arg-tRNA-protein transferase. Arg/N-end rule pathway-dependent degradation of Arg-HSPA5 is a critical regulatory step for autophagosome maturation. Molecular mechanism of Arg/N-end rule dependent autophagic inhibition, oerview
metabolism
the molecular chaperone BiP (also known as GRP78) is short-lived under basal conditions and endoplasmic reticulum (ER) stress. The turnover of BiP is in part driven by its N-terminal arginylation (Nt-arginylation) by arginyltransferase ATE1, which generates an autophagic N-degron of the N-end rule pathway. ER stress elicits the formation of R-BiP, an effect that is increased when the proteasome is also inhibited. Nt-arginylation correlates with the cytosolic relocalization of BiP under the types of stress tested. The cytosolic relocalization of BiP does not require the functionality of the unfolded protein response or the Sec61- or Derlin1-containing translocon. A key inhibitor of the turnover and Nt-arginylation of BiP is HERP (homocysteine-responsive ER protein), a 43-kDa ER membrane-integrated protein that is an essential component of ER-associated protein degradation. Pharmacological inhibition of the ER-Golgi secretory pathway also suppressed R-BiP formation. Cytosolic R-BiP induced by ER stress and proteasomal inhibition is routed to autophagic vacuoles and possibly additional metabolic fates. These results suggest that Nt-arginylation is a posttranslational modification that modulates the function, localization, and metabolic fate of ER-resident proteins

Essential role of N-terminal arginylation in neural tube development. The crucial role of ATE1 in neural tube development is directly related to proper turn-over of the RGS4 protein, which participate in the oxygen-sensing mechanism in the cells. Degradation of the RGS4 protein by ATE1 is closely associated with the migration or differentiation of neural crest cells during embryogenesis. Neural crest cells migrate into the heart and vessels
physiological function
N-terminal arginylation (Nt-arginylation) is a posttranslational modification for which the amino acid L-Arg is conjugated to the Nt-Asp or Nt-Glu residues by ATE1-encoded R-transferases. Nt-arginylation is a posttranslational modification that modulates the function, localization, and metabolic fate of endoplasmic reticulum (ER)-resident proteins. A set of ER-residing molecular chaperones, such as BiP, calreticulin, and PDI, are N-terminally arginylated by enzyme ATE1. Nt-arginylation of BiP is induced in response to cytosolic double-stranded DNA, leading to the cytosolic accumulation of Nt-arginylated BiP, R-BiP. The Nt-Arg residue of R-BiP binds p62 (also known as SQSTM1 and Sequestosome-1) and subsequently is delivered to the autophagosomes for lysosomal degradation. Nt-arginylation mediates the cytosolic relocalization of BiP independently of the functionality of the ERAD core machinery

physiological function
protein arginylation is a posttranlsational modification mediated by arginyltransferase ATE1 that transfers Arg from tRNA directly to protein targets. Protein arginylation targets alpha-synuclein, facilitates normal brain health, and prevents neurodegeneration. Alpha-synuclein (alpha-syn) is a central player in neurodegeneration. It is a highly efficient substrate for arginyltransferase ATE1 and is arginylated in vivo by a mid-chain mechanism that targets the acidic side chains of E46 and E83. alpha-Syn arginylation can be a factor that facilitates normal alpha-syn folding and function in vivo. Arginylation reduces aggregation of pre-formed alpha-syn fibrils and partially prevents alpha-syn-induced seeding of pathological aggregates in cultured neurons, overview

physiological function
the Arg/N-end rule pathway may function to actively protect cells from detrimental effects of cellular stresses, including proteotoxic protein accumulation, by positively regulating autophagic flux. Under endplasmic reticulum (ER) stress, ATE1-encoded Arg-tRNA-protein transferases carry out the N-terminal arginylation of the ER heat shock protein HSPA5 that initially targets cargo proteins, along with SQSTM1, to the autophagosome. At the late stage of autophagy, the proteasomal degradation of arginylated HSPA5 might function as a critical checkpoint for the proper progression of autophagic flux in the cells. N-terminal arginylation by ATE1 is usually sufficient for the recognition by UBR proteins and subsequent ubiquitination and degradation in the Arg/N-end rule pathway. The Arg/N-end rule-mediated autophagic flux regulator might be a direct substrate of ATE1, rather than UBR1 or UBR2
