This enzyme belongs to a class of ubiquitin ligases that include a RING finger motif, and it can interact with the E2 ubiquitin-conjugating enzyme UbcH5B. This gene is located in an area of chromosome X where several X-linked cognitive disability disorders have been associated, and it has also been found as part of a contiguous gene deletion associated with craniofrontonasal syndrome, though a direct link to any disorder has yet to be demonstrated. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]. * **UniProt Summary**: Has E2-dependent E3 ubiquitin-protein ligase activity. Ubiquitinates MAGED1 antigen leading to its subsequent degradation by proteasome (By similarity). May be involved in protein sorting. {ECO:0000250, ECO:0000269|PubMed:12036302}. |zf-rbx1| |zf-C3HC4| |ubiquitin protein ligase activity| |protein catabolic process| |protein ubiquitination| |protein modification by small protein conjugation| |protein modification by small protein conjugation or removal| |macromolecule catabolic process| |organonitrogen compound catabolic process| |organic substance catabolic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp160|Ribavirin 10 to 15μM on day4 R04 exp160]]|1.75| |[[:results:exp510|Nicotine 3000μM R08 exp510]]|1.86| No correlation found to any other genes in chemogenomics.
