Background Information

PTPRS, also known as R-PTP-sigma or PTPσ, is a member of the protein tyrosine phosphatase (PTP) family (PMID: 8524829). PTPs dephosphorylate phosphotyrosyl residues in proteins that are phosphorylated by protein-tyrosine kinases (PTKs) (PMID: 20838449). PTPs are essential regulators of signal transduction pathways and play important roles in regulating many cellular processes in conjunction with PTKs (PMID: 7834742). PTPRS contains an extracellular region, a single transmembrane segment and two tandem intracellular catalytic domains, and thus represents a receptor-type PTP. Full-length PTPRS is 217 kDa and has been reported to be proteolytically cleaved into a 140-kDa N-terminal subunit containing extracellular and transmembrane domains and a C-terminal subunit (PMID: 29915291). This antibody raised against 825-1000 aa of human PTPRS detects endogenous PTPRS with an apparent molecular weight of 140 kDa.
