Protein Information (annotations from UniProt)

Database IDHIV0000147
UniProt IDQ9Y4X5
Primary gene name(s)ARIH1
Synonym gene name(s)ARI, MOP6, UBCH7BP
Protein nameE3 ubiquitin-protein ligase ARIH1
Protein functionE3 ubiquitin-protein ligase, which catalyzes ubiquitination of target proteins together with ubiquitin-conjugating enzyme E2 UBE2L3, PubMed:15236971, PubMed:21532592, PubMed:24076655, PubMed:27565346, PubMed:23707686. Acts as an atypical E3 ubiquitin-protein ligase by working together with cullin-RING ubiquitin ligase, CRL complexes and initiating ubiquitination of CRL substrates: associates with CRL complexes and specifically mediates addition of the first ubiquitin on CRLs targets, PubMed:27565346. The initial ubiquitin is then elongated by CDC34/UBE2R1 and UBE2R2, PubMed:27565346. E3 ubiquitin-protein ligase activity is activated upon binding to neddylated cullin-RING ubiquitin ligase complexes, PubMed:24076655, PubMed:27565346. Plays a role in protein translation in response to DNA damage by mediating ubiquitination of EIF4E2, the consequences of EIF4E2 ubiquitination are however unclear, PubMed:25624349. According to a report, EIF4E2 ubiquitination leads to promote EIF4E2 cap-binding and protein translation arrest, PubMed:25624349. According to another report EIF4E2 ubiquitination leads to its subsequent degradation, PubMed:14623119. Acts as the ligase involved in ISGylation of EIF4E2, PubMed:17289916. {ECO:0000269|PubMed:14623119, ECO:0000269|PubMed:15236971, ECO:0000269|PubMed:17289916, ECO:0000269|PubMed:21532592, ECO:0000269|PubMed:23707686, ECO:0000269|PubMed:24076655, ECO:0000269|PubMed:25624349, ECO:0000269|PubMed:27565346}.
