title: Glycoproteins of the plasma membrane of Dictyostelium discoideum during development.
abstract: Differential binding of 125I-Con A to whole cells throughout the life cycle of dictyostelim discoideum indicates that the appearance of Con A binding proteins on the plasma membrane is under developmental regulation. Con A-Sepharose affinity chromatography of radio-iodinated plasma membrane preparations, followed by analysis with SDS-PAGE, revealed that there are at least 15 Con a binding proteins associated with the surface of 0 hr cells. Between 6 and 18 hr of development, the relative intensity of one of the bands, which corresponds to a protein of molecular weight of 150,000 daltons, increases dramatically.
