Leukocyte common antigen-related receptor protein tyrosine phosphatases--comprising LAR, PTP?, and PTP?--are synaptic adhesion molecules that organize synapse development. Here, we identify glypican 4 (GPC-4) as a ligand for PTP?. GPC-4 showed strong (nanomolar) affinity and heparan sulfate (HS)-dependent interaction with the Ig domains of PTP?. PTP? bound only to proteolytically cleaved GPC-4 and formed additional complex with leucine-rich repeat transmembrane ... [more]
