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. Acts as an adapter for APC/C to target the DNA-end resection factor RBBP8/CtIP for ubiquitination and subsequent proteasomal degradation. Through the regulation of RBBP8/CtIP protein turnover, may play a role in DNA damage response, favoring DNA double-strand repair through error-prone non-homologous end joining (NHEJ) over error-free, RBBP8-mediated homologous recombination (HR) (PubMed:25349192).PATHWAY Protein modification; protein ubiquitination.SUBUNIT The unphosphorylated form interacts with APC/C during mitosis (PubMed:26083744, PubMed:9734353).

Deacetylated by SIRT2 at Lys-69 and Lys-159; deacetylation enhances the interaction of FZR1 with CDC27, leading to activation of anaphase promoting complex/cyclosome (APC/C).PTM Phosphorylated during mitosis, probably by maturation promoting factor (MPF), leading to its dissociation of the APC/C.
