Function: Involved in myofibrillogenesis. Seems to be involved in assembly of myosin into sarcomeric A bands in striated muscle. Isoform 3 together with ANK1 isoform Mu17/Ank1.5 may provide a molecular link between the sarcoplasmic reticulum and myofibrils.
Subcellular Localization: Isoform 3: Cytoplasm, myofibril, sarcomere, M-band. Cytoplasm, myofibril, sarcomere, Z-disk. Note=In differentiating skeletal muscle cells, isoform 3 primarily localizes to the sarcomeric M-line and less frequently to the Z- disk. Isoform 3 colocalizes w
