Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000503
UniProt IDP41002
Primary gene name(s)CCNF
Synonym gene name(s)FBX1, FBXO1
Protein nameCyclin-F
Protein functionSubstrate recognition component of a SCF, SKP1-CUL1-F-box protein E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of CP110 during G2 phase, thereby acting as an inhibitor of centrosome reduplication. {ECO:0000269|PubMed:20596027}.
Subcellular locationNucleus. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole. Note=Localization in the centrosome is rare in S phase cells and increases in G2 cells, Localizes on both the mother and daughter centrioles. Localization to centrosomes is not dependent on CP110. Also localizes to the nucleus.
