Protein 4.1
Protein 4.1,(Erythrocyte membrane protein band 4.1), is aproteinassociated with thecytoskeletonthat in humans is encoded by theEPB41gene.Protein 4.1 is a major structural element of theerythrocytemembraneskeleton. It plays a key role in regulating membrane physical properties of mechanical stability and deformability by stabilizingspectrin-actininteraction. Protein 4.1 (80 kD) interacts with spectrin and shortactin filamentsto form the erythrocyte membrane skeleton. Mutations of spectrin and protein 4.1 are associated withelliptocytosisorspherocytosisandanemiaof varying severity.
Clinical significance
[edit]Elliptocytosis is a hematologic disorder characterized by elliptically shaped erythrocytes and a variable degree of hemolytic anemia. Inherited as an autosomal dominant, elliptocytosis results from mutation in any one of several genes encoding proteins of the red cell membrane skeleton. The form discussed here is the one found in the 1950s to be linked to Rh blood group and more recently shown to be caused by a defect in protein 4.1. 'Rh-unlinked' forms of elliptocytosis are caused by mutation in the alpha-spectringene (MIM 182860), the beta-spectringene (MIM 182870), or theband 3gene (MIM 109270) [supplied by OMIM].[5]
