Previous GeneCards Identifiers for RNF123 Gene
The protein encoded by this gene contains a C-terminal RING finger domain, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions, and an N-terminal SPRY domain. This protein displays E3 ubiquitin ligase activity toward the cyclin-dependent kinase inhibitor 1B which is also known as p27 or KIP1. Alternative splicing results in multiple transcript variants.

RNF123 (Ring Finger Protein 123) is a Protein Coding gene. Among its related pathways are Class I MHC mediated antigen processing and presentation and Deubiquitination. Gene Ontology (GO) annotations related to this gene include ligase activity. An important paralog of this gene is RSPRY1.
UniProtKB/Swiss-Prot Summary for RNF123 Gene
Catalytic subunit of the KPC complex that acts as E3 ubiquitin-protein ligase. Promotes the ubiquitination and proteasome-mediated degradation of CDKN1B which is the cyclin-dependent kinase inhibitor at the G0-G1 transition of the cell cycle (PubMed:15531880, PubMed:16227581). Functions also as an inhibitor of innate antiviral signaling mediated by DDX58 and IFIH1 independently of its E3 ligase activity (PubMed:27312109). Interacts with the N-terminal CARD domains of DDX58 and IFIH1 and competes with the downstream adapter MAVS (PubMed:27312109).
