Scientific background

CHERP (calcium homeostasis endoplasmic reticulum protein) is a ubiquitously expressed integral sarco/endoplasmic reticulum (SR/ER) membrane protein. CHERP protein consist of 916 amino acid in humans and its structure containing a Pro-rich region and a segment of Arg-Ser dipeptide repeats (an RS domain) near the C terminus, and an RNA recognition motifs (RRMs)1-3.

CHERP acts as a regulator of both major families of endoplasmic reticulum Ca2+ channels, inositol 1,4,5-trisphosphate receptors (IP3Rs) and ryanodine receptors (RyRs). CHERP is responsible for the regulation of intracellular Ca2+ mobilization in human cells and is involved in neuroblastoma cell proliferation, apoptosis and tumorigenicity1,2.

CHERP co-localizes with IP3 receptors throughout the cytoplasmic and perinuclear regions in human erythroleukemia cells and in Jurkat cells. CHERP is also detected in the nucleoplasm with prominent accumulation at nuclear speckles1,2. CHERP co-localizes with endogenous ryanodine receptor type 1 (RyR1) in the sarcoplasmic reticulum of rat soleus muscle. Studies of CHERP knockdown reveal decreased intracellular Ca2+ mobilization, cell growth and proliferation2,3.

Application key:

CBE- Cell-based ELISA, FC- Flow cytometry, ICC- Immunocytochemistry, IE- Indirect ELISA, IF- Immunofluorescence, IFC- Indirect flow cytometry, IHC- Immunohistochemistry, IP- Immunoprecipitation, LCI- Live cell imaging, N- Neutralization, WB- Western blot

Species reactivity key:

H- Human, M- Mouse, R- Rat
Last update: 23/08/2020

Anti-CHERP Antibody (#ACC-330) is a highly specific antibody directed against an epitope of the mouse protein. The antibody can be used in western blot and immunohistochemistry applications. It has been designed to recognize CHERP from human, rat, and mouse samples.
