Anti-CASQ1 antibody produced in rabbit

Calsequestrin (CASQ) 1 gene is mapped to human chromosome 1q21, a region associated with type 2 diabetes in Amish and other population. The gene codes for a calcium storage protein, CASQ1, expressed in sarcoplasmic reticulum of fast-twitch skeletal muscle cells.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Calsequestrin (CASQ) 1 is one of the major components of the protein backbone of luminal Ca²⁺ reservoir. It plays a crucial role in calcium flux by regulating calcium channel activity and associating with other proteins localized in the sarcoplasmic reticulum. CASQ1 is involved in insulin- and/or contraction-stimulated glucose transport. Mutation of this gene leads to the accumulation of CASQ1 and other proteins in sarcoplasmic reticulum (SR) vacuole, which results in vacuolar myopathy. Experimental studies on mice shows that CASQ1 is involved in the maintenance of calcium homeostasis and size of terminal cisternae (TC) in skeletal muscle fibers. Alteration in the expression of CASQ1 affects GLUT4 recruitment and insulin sensitivity. Single-nucleotide polymorphisms in the calsequestrin-1 gene act as a genetic marker for graves′ ophthalmopathy (GO) and hashimoto′s thyroiditis (HT).

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
