Protein Function
Uniprot:
Ubiquitin-like protein which can be covalently attached to target lysines as a monomer. Does not seem to be involved in protein degradation and may function as an antagonist of ubiquitin in the degradation process (PubMed:11806825). Plays a role in a number of cellular processes such as nuclear transport, DNA rep
lication and repair, mitosis and signal transduction (PubMed:11806825, PubMed:25475837). Covalent attachment to its substrates requires prior activation by the E1 complex aos-1-uba-2 and linkage to the E2 enzyme ubc-9, and can be promoted by an E3 ligase such as gei-17 (PubMed:15107848, PubMed:16701625). Required for embryonic development, fertility, vulval morphogenesis and inhibition of vulval cell fates (PubMed:15466489, PubMed:15689373, PubMed:15990876, PubMed:24349540). Probably by sumoylating bet-1, prevents muscle myosin depletion in aging adults probably by preventing myoblast growth factor receptor egl-15 overexpression (PubMed:24285704). Plays a role in the attenuation of the let-60/ras pathway (PubMed:24349540, PubMed:24285704).
