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] [ 7]
PTPRA has been shown to interact with Grb2 [ 9] [ 10] [ 11] KCNA2 .[ 12]
