Abstract

Antigen 117 is a glycolipid-anchored cell surface protein implicated in cell-cell cohesion of Dictyostelium discoideum amoebae. Previous studies have demonstrated that during cell aggregation some of the protein is released from the cell surface. Here we report the characterization of the enzymatic activity involved in the 117 antigen release. The data indicate that the releasing enzyme is a phosphatidylinositol phospholipase C. The data also indicate that structural features of glycolipid anchors are conserved in a variety of organisms.
