  • Function

    Protein 4.1 is a major structural element of the erythrocyte membrane skeleton. It plays a key role in regulating membrane physical properties of mechanical stability and deformability by stabilizing spectrin-actin interaction. Recruits DLG1 to membranes.
  • Involvement in disease

    Defects in EPB41 are the cause of elliptocytosis type 1 (EL1) [MIM:611804]. EL1 is a Rhesus-linked form of hereditary elliptocytosis, a genetically heterogeneous, autosomal dominant, hematologic disorder. It is characterized by variable hemolytic anemia and elliptical or oval red cell shape.
    Defects in EPB41 are a cause of hereditary pyropoikilocytosis (HPP) [MIM:266140]. HPP is an autosomal recessive hematologic disorder characterized by hemolytic anemia, microspherocytosis, poikilocytosis, and an unusual thermal sensitivity of red cells.
  • Sequence similarities

    Contains 1 FERM domain.
  • Post-translational

    Phosphorylated at multiple sites by different protein kinases and each phosphorylation event selectively modulates the protein's functions.
    Phosphorylation on Tyr-660 reduces the ability of 4.1 to promote the assembly of the spectrin/actin/4.1 ternary complex.
    O-glycosylated; contains N-acetylglucosamine side chains in the C-terminal domain.
  • Cellular localization

    Cytoplasm > cytoskeleton. Cytoplasm > cell cortex. Nucleus.
