'''
Calsequestrin-2 (or CASQ2) is the soluble CA2+ binding protein in the sarcoplasmic reticulum lumen of the cardiac muscle cells. CASQ2 could be either in a monomeric, homodimeric, or homooligomeric chain form depending on its bounds with Ca2+. Mutations of CASQ2 are involved in cardiac diseases such as Catecholaminergic Polymorphic Ventricular Tachycardia.
