Predicted to enable calcium ion binding activity and ryanodine-sensitive calcium-release channel activity. Involved in locomotion; positive regulation of programmed cell death; and protein localization to organelle. Located in I band and sarcoplasmic reticulum. Expressed in body wall musculature; intestine; neurons; and non-striated muscle. Used to study congenital myopathy 1A and malignant hyperthermia. Human ortholog(s) of this gene implicated in several diseases, including catecholaminergic polymorphic ventricular tachycardia 1; gestational diabetes; and muscle tissue disease (multiple). Is an ortholog of human RYR1 (ryanodine receptor 1); RYR2 (ryanodine receptor 2); and RYR3 (ryanodine receptor 3).
Enables calcium ion binding activity. Involved in calcium ion homeostasis. Located in several cellular components, including apical plasma membrane; nucleus; and sarcolemma. Expressed in body wall musculature; isthmus; terminal bulb; and vulval muscle. Human ortholog(s) of this gene implicated in catecholaminergic polymorphic ventricular tachycardia 2 and type 2 diabetes mellitus. Is an ortholog of human CASQ1 (calsequestrin 1) and CASQ2 (calsequestrin 2).
Enables myosin binding activity. Involved in locomotion; regulation of cytoskeleton organization; and striated muscle myosin thick filament assembly. Located in M band and striated muscle myosin thick filament. Expressed in anal depressor muscle; body wall musculature; and pharyngeal muscle cell.
