"The specific activity of four candidate protein-tyrosine phosphatases (protein-tyrosine phosphatase 1b (ptp1b), sh2 domain-containing ptpase-2 (shp-2), leukocyte common antigen-related (lar), and leukocyte antigen-related phosphatase) (lrp) toward irs-1 dephosphorylation was studied using recombinant proteins in vitro. Ptp1b exhibited the highest specific activity these results provide new insight into novel molecular interactions involving ptp1b and grb2 that may influence the steady-state capacity of irs-1 to function as a phosphotyrosine scaffold and possibly affect the balance of postreceptor insulin signaling."
