The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth , differentiation , mitotic cycle , and oncogenic transformation. This PTP contains an extracellular domain , a single transmembrane segment and two tandem intracytoplasmic catalytic domains , and thus represents a receptor-type PTP. This PTP has been shown to dephosphorylate and activate Src family tyrosine kinases , and is implicated in the regulation of integrin signaling , cell adhesion and proliferation. Three alternatively spliced variants of this gene , which encode two distinct isoforms , have been reported. [provided by RefSeq , Jul 2008] ,
