GeneCards Summary for FZR1 Gene
FZR1 (Fizzy/Cell Division Cycle 20 Related 1) is a Protein Coding gene. Among its related pathways are Cellular Senescence and Cell cycle Role of SCF complex in cell cycle regulation. An important paralog of this gene is CDC20.
UniProtKB/Swiss-Prot for FZR1 Gene
Key regulator of ligase activity of the anaphase promoting complex/cyclosome (APC/C), which confers substrate specificity upon the complex. Associates with the APC/C in late mitosis, in replacement of CDC20, and activates the APC/C during anaphase and telophase. The APC/C remains active in degrading substrates to ensure that positive regulators of the cell cycle do not accumulate prematurely. At the G1/S transition FZR1 is phosphorylated, leading to its dissociation from the APC/C. Following DNA damage, it is required for the G2 DNA damage checkpoint: its dephosphorylation and reassociation with the APC/C leads to the ubiquitination of PLK1, preventing entry into mitosis.
