Function

Attaches integral membrane proteins to cytoskeletal elements; binds to the erythrocyte membrane protein band 4.2, to Na-K ATPase, to the lymphocyte membrane protein GP85, and to the cytoskeletal proteins fodrin, tubulin, vimentin and desmin. Erythrocyte ankyrins also link spectrin (beta chain) to the cytoplasmic domain of the erythrocytes anion exchange protein; they retain most or all of these binding functions. {ECO:0000269PubMed:12456646}.Isoform Mu17 together with obscurin in skeletal muscle may provide a molecular link between the sarcoplasmic reticulum and myofibrils. {ECO:0000269PubMed:12456646}.

Subcellular Localization

Isoform Er1: Cytoplasm, cytoskeleton. Note=Probably the other erythrocyte (Er) isoforms, are located near the surface of erythrocytic plasma membrane.Isoform Mu17: Membrane. Cytoplasm, myofibril, sarcomere, M line. Note=Colocalizes with OBSCN isoform 3/obscurin at the M line in differentiated skeletal muscle cells.Isoform Mu18: Sarcoplasmic reticulum {ECO:0000305}.Isoform Mu19: Sarcoplasmic reticulum {ECO:0000305}.Isoform Mu20: Sarcoplasmic reticulum {ECO:0000305}.

Disease Associations

Spherocytosis 1 (SPH1) [MIM:182900]: Spherocytosis is a hematologic disorder leading to chronic hemolytic anemia and characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. SPH1 is characterized by severe hemolytic anemia. Inheritance is autosomal recessive. {ECO:0000269PubMed:11102985, ECO:0000269PubMed:8640229}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

Isoform Mu17, isoform Mu18, isoform Mu19 and isoform Mu20 are expressed in skeletal muscle. Isoform Br21 is expressed in brain. {ECO:0000269PubMed:9430667}.
