Recombinant Human E3 ubiquitin-protein ligase RNF14 (RNF14)

Uniprot Id

Q9UBS8

Target Species

Human

Target Name

RNF14

Target Full Name

E3 ubiquitin-protein ligase RNF14

Target Function

Might act as an E3 ubiquitin-protein ligase which accepts ubiquitin from specific E2 ubiquitin-conjugating enzymes and then transfers it to substrates, which could be nuclear proteins. Could play a role as a coactivator for androgen- and, to a lesser extent, progesterone-dependent transcription.

Target Subcellular Location

Cytoplasm. Nucleus.

Target Protein Families

RBR family, RNF14 subfamily

Target Tissue Specificity

Widely expressed.

Target Synonyms

Target Background

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. Six alternatively spliced transcript variants encoding two distinct isoforms have been reported.
