FUNCTION: 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. PATHWAY: Protein modification; protein ubiquitination. SUBUNIT: The unphosphorylated form interacts with APC/C during mitosis. Interacts with NINL. Interacts (in complex with the anaphase promoting complex APC) with MAD2L2; inhibits FZR1- mediated APC/C activation. Interacts with USP37. Interacts (via WD repeats) with MAK. SUBCELLULAR LOCATION: Isoform 2: Nucleus. SUBCELLULAR LOCATION: Isoform 3: Cytoplasm. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=3; Name=1; IsoId=Q9UM11-1; Sequence=Displayed; Name=2; Synonyms=CDH1alpha, Fzr1; IsoId=Q9UM11-2; Sequence=VSP_008504; Note=Major; Name=3; Synonyms=CDH1beta, Fzr2; IsoId=Q9UM11-3; Sequence=VSP_008503, VSP_008504; Note=Minor; TISSUE SPECIFICITY: Isoform 2 is expressed at high levels in heart, liver, spleen and some cancer cell lines whereas isoform 3 is expressed only at low levels in these tissues. PTM: Phosphorylated during mitosis, probably by maturation promoting factor (MPF), leading to its dissociation of the APC/C. Following DNA damage, it is dephosphorylated by CDC14B in G2 phase, leading to its reassociation with the APC/C, and allowing an efficient G2 DNA damage checkpoint. Phosphorylated by MAK. SIMILARITY: Belongs to the WD repeat CDC20/Fizzy family. SIMILARITY: Contains 7 WD repeats. SEQUENCE CAUTION: Sequence=AAD26623.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence.
