Protein

Protein tyrosine phosphatase type IVA 3

Gene

PTP4A3

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. May be involved in the progression of cardiac hypertrophy by inhibiting intracellular calcium mobilization in response to angiotensin II (By similarity).By similarity

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Enzyme regulationi

Inhibited by sodium orthovanadate and peroxovanadium compounds, and by pentamidine.By similarity
