Ubiquitin protein ligase

From Proteopedia

Template:STRUCTURE 1c4z

Ubiquitin-protein ligase (UPL) (E3)in combination with ubiquitin-conjugating enzyme (E2) causes the attachment of ubiquitin to lysine to a target protein. UPL XIAP or X-linked Inhibitor of Apoptosis Protein stops apoptosis induced by viral infection or by overproduction of caspases. UPL XIAP or baculoviral IAP repeat-containing protein, binds caspase-3, -7 and -9. UPL can contain several distinct domains like: WW domains which contains 2 tryptophans which bind proline-rich peptide; UBA – Ubiquitin-Associated Domain; TKB – Tyrosine Kinase Binding domain; C2 – an 8 β strand domain which coordinates targeting proteins toward cell membrane; HECT – Homologous to the E6-AP Carboxyl Terminus; RING – Really Intersting New Gene involved in binding to E2; FHA – Forkhead Associated domain recognizing phosphothreonine; IBR – involved in binding to E2; PHD finger – Plant Homeo Domain is 50-80 amino acid long which contains a CHC motif; SRA – SET and RING-Associated domain; TUDOR – is a ca. 50 amino acids long and recognizes dimethylated arginine; CPH – protein-protein interaction domain; UBR – a ca. 70 amino acid long zinc finger-like domain; CUE – a ubiquitin-binding domain. UPL XIAP consists of 3 BIR (baculoviral IAP repeat) domains, followed by UBA (ubiquitin-binding) domain and RING (C-terminal RING finger) domain. BIR2 inhibits caspase-3 and -7. BIR3 inhibits caspase-9. Overexpression of UPL XIAP functions as tumor marker. UPL XIAP is inhibited by Smac – a death signaling protein. For some details see
