  • 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.

  • EPB41 antibody (ab54597) used in immunohistochemistry at 3ug/ml on formalin fixed and paraffin embedded human colon.
  • Western blot against tagged recombinant protein immunogen using ab54597 EPB41 antibody at 1ug/ml. Predicted band size of immunogen is 38 kDa.

    This antibody has only been tested in WB against the recombinant fragment used as immunogen. We have no data on the detection of endogenous protein.

  • ab54597 at 10 µg/ml staining EPB41 in human Hella cells by Immunocytochemistry / Immunofluorescence.

  • Overlay histogram showing K562 cells stained with ab54597 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab54597, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in K562 cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
