In vivo sulfation of the contact site A glycoprotein of Dictyostelium discoideum.


During the development of Dictyostelium discoideum from the growth phase to the aggregation stage, a glycoprotein with an apparent mol. wt. of 80 kd is known to be expressed on the cell surface. This glycoprotein, referred to as contact site A, has been implicated in the formation of species-specific, EDTA-stable contacts of aggregating cells. When… (More)
