Protein Information (annotations from UniProt)

Database IDHIV0006813
UniProt IDQ9UBF6
Primary gene name(s)RNF7
Synonym gene name(s)RBX2, ROC2, SAG
Protein nameRING-box protein 2
Protein functionProbable component of the SCF, SKP1-CUL1-F-box protein E3 ubiquitin ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins involved in cell cycle progression, signal transduction and transcription, PubMed:10851089. CRLs complexes and ARIH1 collaborate in tandem to mediate ubiquitination of target proteins, ARIH1 mediating addition of the first ubiquitin on CRLs targets, By similarity. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate. Promotes the neddylation of CUL5 via its interaction with UBE2F. May play a role in protecting cells from apoptosis induced by redox agents. {ECO:0000250|UniProtKB:P62877, ECO:0000269|PubMed:10851089}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:10082581}. Nucleus {ECO:0000269|PubMed:10082581}.
