Bacitracin reveals a role for multiple thiol isomerases in platelet function.

Abstract

The platelet-specific integrin alphaIIb beta3 has endogenous thiol isomerase activity associated with the CXXC motifs within the beta subunit. Using a highly purified form of bacitracin, a thiol isomerase inhibitor, we now provide further evidence of the functional significance of this enzymatic activity in integrin activation. In addition, we demonstrate a… (More)
