title: A beta 1 integrin-like molecule in Entamoeba histolytica.
abstract: Human invasive amoebiasis is highly destructive, causing rapid necrosis and liquefaction of all tissues reached by the trophozoites. Degradation of extracellular matrix components (EMC) has been demonstrated during invasion of the basal lamina. Pursuing the idea that trophozoites might behave similarly to other invasive cells with respect to their interaction with EMC, plasma membrane proteins biochemically or functionally related to integrins were looked for. A 140 kDa molecular mass membrane protein from Entamoeba histolytica trophozoites with the characteristics of a beta 1 integrin-like fibronectin receptor was identified.
