RNF123 Catalytic subunit of the KPC complex that acts as E3 ubiquitin-protein ligase. Required for poly-ubiquitination and proteasome-mediated degradation of CDKN1B during G1 phase of the cell cycle. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
