Skeletal muscle dressed in SOCs

store-operated Ca(2+) channels (sOCs) are activated in response to Ca2+ release from the endoplasmic reticulum (ER). The stromal interaction molecule 1 (STIM1) is the ER sensor that transmits the stored Ca2+ content to the pore- forming sOCs Orai and TRPC channels. Recent studies reveal high levels of Orai1 and STIM1 in skeletal muscle, and a prominent role of sOCs in muscle development and function.
