Protein tyrosine phosphatase type IVA 1

Gene

PTP4A1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. May play a role in the development and maintenance of differentiating epithelial tissues. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis.3 Publications

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.1 Publication

Enzyme regulationi

Inhibited by sodium orthovanadate and pentamidine.1 Publication
