Receptor-type tyrosine-protein phosphatase alpha is an enzyme that in humans is encoded by the PTPRA gene. [5] [6] [7]
The protein encoded by this gene is a member of the receptor tyrosine phosphatases (RTP), a family of protein tyrosine phosphatases. RTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This RTP contains an extracellular domain, a single transmembrane segment and two tandem intracytoplasmic catalytic domains, and thus represents a receptor-type RTP. This RTP has been shown to dephosphorylate and activate Src family tyrosine kinases, [8] 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. [7]
PTPRA has been shown to interact with Grb2 [9] [10] [11] and KCNA2. [12]
