Official Full Name protein tyrosine phosphatase type IVA, member 2
Background The protein encoded by this gene belongs to a small class of the protein tyrosine phosphatase (PTP) family. PTPs are;cell signaling molecules that play regulatory roles in a variety of cellular processes. PTPs in this class contain a;protein tyrosine phosphatase catalytic domain and a characteristic C-terminal prenylation motif. This PTP has been;shown to primarily associate with plasmic and endosomal membrane through its C-terminal prenylation. This PTP was;found to interact with the beta-subunit of Rab geranylgeranyltransferase II (beta GGT II), and thus may function as a;regulator of GGT II activity. Overexpression of this gene in mammalian cells conferred a transformed phenotype, which;suggested its role in tumorigenesis. Alternatively spliced transcript variants have been described. Related;pseudogenes exist on chromosomes 11, 12 and 17.
