Component of a complex of multiple actin cross-linking proteins. Involved in the control of myofibril assembly and stability at the Z lines in muscle cells.
Subcellular locations: Cell membrane, Sarcolemma, Cytoplasm, Cytoskeleton, Cytoplasm, Myofibril, Sarcomere, Z line
Sarcomeric, also localized to the sarcolemma . Colocalizes with MYOZ1 at the Z-lines in skeletal muscle .
Expressed in skeletal muscle (at protein level). Expressed in skeletal muscle, heart, bone marrow and thyroid gland.
