RNF14

E3 ubiquitin-protein ligase RNF14 is an is_associated_with::enzyme that in humans is encoded by the RNF14 is_associated_with::gene.

Function
The protein encoded by this gene contains a RING zinc finger, a motif known to be involved in protein-protein interactions. This protein interacts with androgen receptor (AR) and may function as a coactivator that induces AR target gene expression in prostate. A dominant negative mutant of this gene has been demonstrated to inhibit the AR-mediated growth of prostate cancer. This protein also interacts with class III ubiquitin-conjugating enzymes (E2s) and may act as a ubiquitin-ligase (E3) in the ubiquitination of certain nuclear proteins. Five alternatively spliced transcript variants encoding two distinct isoforms have been reported.

Interactions
RNF14 has been shown to interact with the is_associated_with::Androgen receptor.
