PTPRM (Receptor-type Tyrosine-protein Phosphatase mu, Protein-tyrosine Phosphatase mu, R-PTP-mu, PTPRL1)

PTP mu, a R2A receptor 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 possesses an extracellular region, a single transmembrane region, and two tandem catalytic domains, and thus represents a receptor-type PTP. The extracellular region contains a meprin-A5 antigen-PTP mu (MAM) domain, an Ig-like domain and four fibronectin type III-like repeats. This PTP has been shown to mediate cell-cell aggregation through the interaction with another molecule of this PTP on an adjacent cell. This PTP can interact with scaffolding protein RACK1/GNB2L1, which may be necessary for the downstream signaling in response to cell-cell adhesion. The Human PTP mu gene is localized on chromosome 18pter-q11, a region with frequent abnormalities implicated in Human cancer. PTP mu may be important in responses to pathological conditions associated with the loss of cell-cell interactions in the heart.\n\nApplications:\nSuitable for use in ELISA.
