Protein: Ankyrin-1 (ANK-1) (Ankyrin-R) (Erythrocyte ankyrin) (P16157)
Organism: Homo sapiens (Human)
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.
Subcellular location: [Isoform Er1]: Cytoplasm, cytoskeleton. Note=Probably the other erythrocyte (Er) isoforms, are located near the surface of erythrocytic plasma membrane.; SUBCELLULAR LOCATION: [Isoform Mu17]: Membrane. Cytoplasm, myofibril, sarcomere, M line. Note=Colocalizes with OBSCN isoform 3/obscurin at the M line in differentiated skeletal muscle cells.; SUBCELLULAR LOCATION: [Isoform Mu18]: Sarcoplasmic reticulum {ECO:0000305}.; SUBCELLULAR LOCATION: [Isoform Mu19]: Sarcoplasmic reticulum {ECO:0000305}.; SUBCELLULAR LOCATION: [Isoform Mu20]: Sarcoplasmic reticulum {ECO:0000305}.
