E3 ubiquitin-protein ligase RNF128 is an enzyme that in humans is encoded by the RNF128 gene.^[3]

The protein encoded by this gene is a type I transmembrane protein that localizes to the endocytic pathway. This protein contains a RING zinc-finger motif and has been shown to possess E3 ubiquitin ligase activity. Expression of this gene in retrovirally transduced T cell hybridoma significantly inhibits activation-induced IL2 and IL4 cytokine production. Induced expression of this gene was observed in anergic CD4(+) T cells, which suggested a role in the induction of anergic phenotype. Alternatively spliced transcript variants encoding distinct isoforms have been reported.^[3]

Interactions

RNF128 has been shown to interact with CD154^[4] and OTUB1.^[5]
