ATE1 plays an important role a specialized ubiquitin mediated protein degradation pathway. ATE1 is involved in the post-translational conjugation of arginine to the N-terminal or mid-chain Aspartate or Glutamate amino acids of proteins. The arginylation is required for effective ubiquitin mediated protein degradation. ATE1 is a central player in the Arg/N-end rule pathway of ubiquitin mediated protein degradation. This system disposes of malformed or misdirected proteins and protein fragments. ATE1 has two isoforms, isoform 1 is nuclear localized and isoform 2 is cytoplasmically localized. ATE1 is widely expressed, and recent research demonstrates that ATE1 mediated arginylation is essential for platelet myosin phosphorylation, clot retraction and thrombosis formation. Recent research also shows that the Arg/N-end rule pathway and ATE1 may play a role in helping to prevent neurodegeneration caused by the buildup of protein fragments found in various neurological disease states such as Alzheimer's disease, amyotrophic lateral sclerosis, and Parkinson's disease.
