Template:PBB Ryanodine receptor 1 (RYR-1) also known as skeletal muscle calcium release channel or skeletal muscle-type ryanodine receptor is a protein found primarily in skeletal muscle. In humans, it is encoded by the RYR1 gene.[1][2]

Function

RYR1 functions as a calcium release channel in the sarcoplasmic reticulum, as well as a connection between the sarcoplasmic reticulum and the transverse tubule.[3] The channel is associated with the dihydropyridine receptor of the sarcoplasmic reticulum, which opens in response to depolarization and thus effectively means that the RYR1 channel opens in response to depolarization of the cell.

Clinical significance

Mutations in the RYR1 gene are associated with malignant hyperthermia susceptibility, central core disease, minicore myopathy with external ophthalmoplegia and samaritan myopathy, a benign congenital myopathy.[4] Alternatively spliced transcripts encoding different isoforms have been demonstrated.[3] Dantrolene may be the only known drug that is effective during cases of malignant hyperthermia.[citation needed]

Interactions

RYR1 has been shown to interact with:
