4.1R-deficient human red blood cells have altered phosphatidylserine exposure pathways and are deficient in CD44 and CD47 glycoproteins
Background Protein 4.1R is an important component of die red cell membrane skeleton. It imparts structural integrity and has transmembrane signaling roles by direct interactions with transmembrane proteins and other membrane skeletal components, notably p55 and calmodulin. Design and Methods Spontaneous and ligation-induced phosphatidylserine exposure on erythrocytes from two patients with 4.1R de
