Protein Information (annotations from UniProt)

Database IDHIV0000551
UniProt IDP30305
Primary gene name(s)CDC25B
Synonym gene name(s)CDC25HU2
Protein nameM-phase inducer phosphatase 2
Protein functionTyrosine protein phosphatase which functions as a dosage-dependent inducer of mitotic progression. Required for G2/M phases of the cell cycle progression and abscission during cytokinesis in a ECT2-dependent manner. Directly dephosphorylates CDK1 and stimulates its kinase activity. The three isoforms seem to have a different level of activity. {ECO:0000269|PubMed:17332740}.
Subcellular locationCytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000269|PubMed:15128871, ECO:0000269|PubMed:15311285, ECO:0000269|PubMed:15908796}. Cytoplasm, cytoskeleton, spindle pole {ECO:0000269|PubMed:15908796}.
