Protein tyrosine phosphatase type IVA 3 is an enzyme that in humans is encoded by the PTP4A3 gene.The protein encoded by this gene belongs to a small class of prenylated protein tyrosine phosphatases (PTPs). PTPs are cell signaling molecules that play regulatory roles in a variety of cellular processes. This class of PTPs contain a PTP domain and a characteristic C-terminal prenylation motif.
