Supplementary information

RNF123 also known as KPC1 is an E3 ubiquitin-protein ligase with a molecular mass of approximately 178 kDa. It plays an important role in the ubiquitination process which tags proteins for degradation by the proteasome. RNF123 is widely expressed in human tissues with notable expression in the brain heart and lungs. It functions through its RING finger domain an essential component in the recognition and transfer of ubiquitin molecules to substrate proteins.
Biological function summary

RNF123 modulates cellular function through its ability to control protein turnover. As part of the Skp1-Cullin-F-box (SCF) complex it influences cellular processes such as the cell cycle by regulating proteolytic degradation of proteins. The ligase activity of RNF123 directly contributes to the balance of cellular components impacting cell cycle progression and apoptosis regulation. Its involvement in apoptotic pathways captures attention where it influences cell survival by targeting specific substrates for degradation.

Pathways

RNF123 interacts within the ubiquitin-proteasome pathway and the cell cycle regulation pathways. By fine-tuning the degradation of cyclins and cyclin-dependent kinase inhibitors RNF123 works closely with proteins such as Skp1 and Cullin to ensure proper cell cycle progression. It also impacts pathways related to cell signaling by influencing the turnover of signaling molecules which is important for maintaining cellular homeostasis.

Researchers associate RNF123 with cancer progression and neurodegenerative diseases. Its dysregulation has been linked to the development of certain cancers where it affects the stability of tumor suppressor proteins. Moreover in neurodegenerative disorders such as Alzheimer's RNF123's role in protein homeostasis suggests connections to disease pathogenesis by interacting with proteins like Tau. Understanding RNF123's role in these conditions offers insights into potential therapeutic targets.

Target data

Catalytic subunit of the KPC complex that acts as E3 ubiquitin-protein ligase (PubMed : 15531880, PubMed : 16227581, PubMed : 25860612). 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). Also acts as a key regulator of the NF-kappa-B signaling by promoting maturation of the NFKB1 component of NF-kappa-B : acts by catalyzing ubiquitination of the NFKB1 p105 precursor, leading to limited proteasomal degradation of NFKB1 p105 and generation of the active NFKB1 p50 subunit (PubMed : 25860612, PubMed : 33168738, PubMed : 34873064). Also functions as an inhibitor of innate antiviral signaling mediated by RIGI and IFIH1 independently of its E3 ligase activity (PubMed : 27312109). Interacts with the N-terminal CARD domains of RIGI and IFIH1 and competes with the downstream adapter MAVS (PubMed : 27312109).
