Genes affected

COP1 (HGNC:17440): (COP1 E3 ubiquitin ligase) Enables ubiquitin protein ligase activity. Involved in positive regulation of proteasomal ubiquitin-dependent protein catabolic process; proteasome-mediated ubiquitin-dependent protein catabolic process; and response to ionizing radiation. Part of Cul4A-RING E3 ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]
