E3 ubiquitin protein ligase RNF128, E3 ubiquitin-protein ligase RNF128, FLJ23516, Gene related to anergy in lymphocytes protein, GRAIL, ring finger protein 128, RN128_HUMAN, RNF128.
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. [provided by RefSeq, Jul 2008].
