Protein
M-phase inducer phosphatase 2
Gene
Cdc25b, Cdc25m2
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at transcript leveli

Functioni

Tyrosine 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 By similarity.

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Enzyme regulationi

Stimulated by B-type cyclins.

Post-translational modificationi

Phosphorylated by BRSK1 in vitro. Phosphorylated by CHEK1, which inhibits the activity of this protein. Phosphorylation at Ser-351 by AURKA might locally participate in the control of the onset of mitosis. Phosphorylation by MELK at Ser-167 promotes localization to the centrosome and the spindle poles during mitosis. Phosphorylation at Ser-321 and Ser-372 by MAPK14 is required for binding to 14-3-3 proteins By similarity.

Expressioni

Tissue specificityi

Expressed predominantly in spleen, lung, heart, brain, intestine, and muscle.

Developmental stagei

Detected at the one-cell stage followed by a decrease in signal intensity at the two-cell stage. Detectable at higher level in the four-cell stage and expressed through the eight-cell, 16-cell and morula stages. Maximal expression at the blastocyst stage.
