Application

Anti-RNF123, clone 2C10.1, Cat. No. MABS1896, is a mouse monoclonal antibody that detects RING-type E3 ubiquitin transferase RNF123 and has been tested for use in Western Blotting.

General description

E3 ubiquitin-protein ligase RNF123 (UniProt: Q5XPI4; also known as EC 2.3.2.27, Kip1 ubiquitination-promoting complex protein 1, RING finger protein 123, RING-type E3 ubiquitin transferase RNF123) is encoded by the RNF123 (also known as KPC1, PF1477) gene (Gene ID: 63891) in human.RNF123 serves as a catalytic subunit of the KPC complex that acts as E3 ubiquitin-protein ligase. It is required for poly-ubiquitination and proteasome-mediated degradation of CDKN1B/p27 during the cell cycle G1 phase of the cell cycle. It contains a ring-type zinc finger domain (aa 1254-1292). Two isoforms of RNF123 have been reported that are produced by alternative splicing. RNF123 is also reported to serve as a negative regulator of RIG-I and MDA5. Overexpression of RNF123 is shown to inhibit IFN-beta production triggered by Sendai virus (SeV) and encephalomyocarditis picornavirus (EMCV) and knockdown of endogenous RNF123 can potentiate IFN-beta production triggered by SeV and EMCV. RNF123 is shown to interact with the N-terminal CARD domains of RIG-I/MDA5 and compete with the downstream adaptor VISA/MAVS/IPS-1/Cardif for RIG-I/MDA5 CARD binding. (Ref.: Wang, S., et al. (2016). EMBO Rep. 17(8):1155-68).
