Interactioni

Subunit structurei

Component of the probable ECS(SPSB2) E3 ubiquitin-protein ligase complex which contains CUL5, RNF7/RBX2, Elongin BC complex and SPSB2 (PubMed:15601820). Interacts with CUL5, RNF7, ELOB and ELOC (PubMed:15601820). Interacts with MET (PubMed:15713673). Interacts (via B30.2/SPRY domain) with PAWR; this interaction occurs in association with the Elongin BC complex (PubMed:16498413, PubMed:20561531).4 Publications
