Automated description from the Alliance of Genome Resources (Release 4.0)
Enables protease binding activity; ryanodine-sensitive calcium-release channel activity; and voltage-gated calcium channel activity. Involved in animal organ development; cellular response to caffeine; and release of sequestered calcium ion into cytosol by sarcoplasmic reticulum. Acts upstream of or within muscle contraction and release of sequestered calcium ion into cytosol. Located in T-tubule; sarcoplasmic reticulum membrane; and smooth endoplasmic reticulum. Part of junctional membrane complex. Is expressed in several structures, including brain; embryo mesenchyme; endocrine gland; heart; and skeletal musculature. Used to study central core disease and malignant hyperthermia. Human ortholog(s) of this gene implicated in central core disease; malignant hyperthermia; and multiminicore disease. Orthologous to human RYR1 (ryanodine receptor 1).
