Cell division control protein 4

UniProtKB accession:  P07834

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and binds to phosphorylated target proteins. Directs ubiquitination of the phosphorylated CDK inhibitor SIC1. Involved in the degradation of CDC6 together with CDC34/UBC3 and CDC53, and in restricting the degradation of FAR1 to the nucleus. Is essential for initiation of DNA replication and separation of the spindle pole bodies to form the poles of the mitotic spindle. It also plays a role in bud development, fusion of zygotic nuclei after conjugation and various aspects of sporulation. Required for HTA1-HTB1 locus transcription activation. Required for G1/S and G2/M transition.
