PTPases are responsible for dephosphorylation of the insulin receptor and its substrates, and hence, turning off the insulin signal. To date, no insulin receptor-specific phosphatase has been identified. Total membrane-bound tyrosine phosphatase activity is increased in skeletal muscle of type 2 diabetic patients (158). Immunodepletion experiments in muscles from these diabetic patients and obese individuals suggest that especially two phosphatases, protein-tyrosine phosphatase 1B (PTP-1B) and leukocyte antigen-related (LAR) phosphatase, are mainly responsible for this increase (159)." ; prov:wasQuotedFrompubmed:10194465 . sub:_4rdfs:label "Selventa" . sub:assertionprov:hadPrimarySourcepubmed:10194465 ; prov:wasDerivedFrombeldoc: , sub:_3 . }
