ring finger protein 216

Also known as: CAHH, TRIAD3, U7I1, UBCE7IP1, ZIN

NCBI Gene: 54476 ENSG00000011275 UniProt: Q9NWF9 OMIM: 609948

RNF216 encodes an E3 ubiquitin ligase that transfers ubiquitin to substrates promoting their degradation, regulating processes including antiviral responses, autophagy, synaptic plasticity, and gonadotropin-releasing hormone signaling. Autosomal recessive mutations cause cerebellar ataxia and hypogonadotropic hypogonadism, affecting both the nervous system and reproductive endocrine function. The gene is highly constrained against loss-of-function variants in the population.

OMIM ResearchSummary from RefSeq, OMIM, UniProt

This gene encodes a cytoplasmic protein which specifically colocalizes and interacts with the serine/threonine protein kinase, receptor-interacting protein (RIP). Zinc finger domains of the encoded protein are required for its interaction with RIP and for inhibition of TNF- and IL1-induced NF-kappa B activation pathways. The encoded protein may also function as an E3 ubiquitin-protein ligase which accepts ubiquitin from E2 ubiquitin-conjugating enzymes and transfers it to substrates. Several alternatively spliced transcript variants have been described for this locus but the full-length natures of only some are known. [provided by RefSeq, Jul 2008]
