PDB 7RW4  (X-ray  1.31A 
DBSNP rs16938829  rs16938828 
Subcellular location [CC]Cell membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250}. Endoplasmic reticulum membrane {ECO:0000250};
Single-pass type IV membrane protein {ECO:0000250}. Sarcoplasmic reticulum membrane {ECO:0000250};
Single-pass type IV membrane protein {ECO:0000250}. Note=Localized predominantly on the plasma membrane. The transmembrane domain is anchored in endoplasmic/sarcoplasmic reticulum membrane, while the N-terminal part associates with the plasma membrane. In skeletal muscle cells, it is predominantly localized at the junction of the A and I bands (By similarity). {ECO:0000250}.
