Protein

Protein tyrosine phosphatase type IVA 2

Gene

Ptp4a2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Protein tyrosine phosphatase which stimulates progression from G1 into S phase during mitosis. Inhibits geranylgeranyl transferase type II activity by blocking the association between RABGGTA and RABGGTB (By similarity).By similarity

Catalytic activityi

Protein tyrosine phosphate + H2O = protein tyrosine + phosphate.

Enzyme regulationi

Inhibited by sodium orthovanadate and pentamidine.By similarity
