Protein

M-phase inducer phosphatase 1-B

Gene

cdc25-1-b

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

This protein functions as a dosage-dependent inducer in mitotic control. It is a tyrosine protein phosphatase required for progression of the cell cycle. It may directly dephosphorylate p34(cdc2) and activate the p34(cdc2) kinase activity.

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.
