Product Information

Symbol/Gene Name:  CUL5

Alias:  Cullin-5,CUL-5,Vasopressin-activated calcium-mobilizing receptor 1,VACM-1

Uniprot: Q93034

Background: Core component of multiple SCF-like ECS (Elongin-Cullin 2/5-SOCS-box protein) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination and subsequent proteasomal degradation of target proteins (PubMed:11384984, PubMed:15601820). As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme (PubMed:11384984, PubMed:15601820). The functional specificity of the E3 ubiquitin-protein ligase complex depends on the variable substrate recognition component (PubMed:11384984, PubMed:15601820). ECS(SOCS1) seems to direct ubiquitination of JAK2 (PubMed:11384984). ECS(KLHDC1) complex is part of the DesCEND (destruction via C-end degrons) pathway and mediates ubiquitination and degradation of truncated SELENOS selenoprotein produced by failed UGA/Sec decoding, which ends with a glycine (PubMed:32200094). May form a cell surface vasopressin receptor (PubMed:9037604).
