UniProt ID: A0A8M2B4G4 |
FUNCTION: E3 ubiquitin-protein ligase which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes, and transfers it to substrates, generally promoting their degradation by the proteasome. {ECO:0000256|RuleBase:RU367001}. CATALYTIC ACTIVITY: Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L- cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.; EC=2.3.2.27; Evidence={ECO:0000256|ARBA:ARBA00000900, ECO:0000256|RuleBase:RU367001}; PATHWAY: Protein modification; protein ubiquitination. {ECO:0000256|ARBA:ARBA00004906, ECO:0000256|RuleBase:RU367001}. DOMAIN: The N-terminus is composed of the phosphotyrosine binding (PTB) domain, a short linker region and the RING-type zinc finger. The PTB domain, which is also called TKB (tyrosine kinase binding) domain, is composed of three different subdomains: a four-helix bundle (4H), a calcium-binding EF hand and a divergent SH2 domain. {ECO:0000256|RuleBase:RU367001}. |
