Anti-CHRM1 antibody produced in rabbit

General description

The gene CHRM1 (cholinergic receptor, muscarinic 1) encodes a muscarinic cholinergic receptor that is the most abundant muscarinic receptor in the CNS (central nervous system). It is predominantly expressed in the neurons. It is a member of the muscarinic acetylcholine receptor family that conatins five subtypes, CHRM1-CHRM5. These subtypes have high homology but differ in signal transduction mediated via G protein-coupled pathways, resulting in varying physiological responses. The subtypes CHRM1, CHRM3, and CHRM5 have affinity for G proteins of the Gq/11 family and CHRM2 and CHRM4 bind to Gi/o-type G proteins. The gene is mapped to human chromosome 11q13.

Immunogen

Muscarinic acetylcholine receptor M1 recombinant protein epitope signature tag (PrEST)

Application

Anti-CHRM1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

The protein encoded by the gene CHRM1 (cholinergic receptor, muscarinic 1) stimulates intracellular Ca²⁺ signaling in response to acetylcholine in striatal cells. The expression of this protein is modulated by heterochromatin condensation and any changes in its structure leads to impaired Ca²⁺ release from ER. The encoded protein enhances phosphatidylinositol (PtdIns) hydrolysis and mobilization of intracellular Ca²⁺. Both CHRM1 and CHRM2 are involved in regulating cholinergic action on glutamatergic and GABAergic nerve terminals in the stiratum and this system has been associated with HD (Huntington′s disease) pathology.

Features and Benefits

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.
