Disclosed is a novel protein designated platelet secretory transport protein (PSTP). PSTP occurs in platelets and binds to syntaxin. An isolated DNA encoding PSTP, vectors and cells containing the DNA, and PSTP specific antibodies are also disclosed. A PSTP antibody can be used to target a compound to an activated platelet in a mammal for diagnostic or therapeutic purposes. Also disclosed is an in vitro screening method for identifying a compound that inhibits PSTP-syntaxin binding, and an in vitro method for identifying a compound that inhibits PSTP gene expression. |
