Protein tyrosine phosphatase type IVA 1 is an enzyme that in humans is encoded by the PTP4A1 gene.The protein encoded by this gene belongs to a small class of prenylated protein tyrosine phosphatases (PTPs) which contains a PTP domain and a characteristic C-terminal prenylation motif. PTPs are cell signaling molecules that play regulatory roles in a variety of cellular processes. This tyrosine phosphatase is a nuclear protein but may primarily associate with plasma membrane.
