Descripción

General description

Calsequestrin (CS also known as CSQ), the major Ca²⁺ binding protein in cardiac and skeletal muscle, is a high-capacity, low-affinity Ca²⁺ binding glycoprotein, which functions as an internal Ca²⁺ store in the lumen of the SR. In mammalians, two forms of the protein are found, calsequestrin-1 (CASQ-1) and calsequestrin-2 (CASQ-2), which encode the fast-twitch skeletal muscle and cardiac calsequestrin, respectively. Calsequestrin-1 is found in the SRs terminal cisternae luminal space of fast skeletal muscle cells. Calsequestrin-1 is a putative autoantigen associated with eye muscle inflammation in Graves′ disease.

Immunogen

synthetic peptide corresponding to amino acids 28-45 located near the N-terminus of mouse calsequestrin-1, conjugated to KLH. This sequence is identical in rat and highly conserved in human and bovine calsequestrin-1 (two amino acid substitution). This sequence is not found in calsequestrin-2.

Application

Anti-Calsequestrin-1 (N-terminal) antibody produced in rabbit is suitable for western blotting at a concentration of 0.5-1μg/mL using extracts of rat skeletal muscle S1 fraction.

Biochem/physiol Actions

Calsequestrin (CS) is a calcium-binding protein in the sarcoplasmic reticulum (SR). It is known as CSQ and PDIB1. The gene belongs to calsequestrin protein family. Calsequestrin-1 is a putative auto-antigen associated with eye muscle inflammation in Graves′ disease. Calsequestrin-2 (55 kDa) is found in the SR′s terminal cisternae luminal space of cardiac, slow skeletal muscle cells and may be in platelets. The major Ca2+ binding protein in cardiac and skeletal muscle is a high-capacity, low-affinity Ca2+ binding glycoprotein, which functions as an internal Ca2+ store in the lumen of the SR. It helps in controlling the smooth-muscle contraction.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
