Application

Anti-CHM 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

CHM (choroideremia) gene encodes a protein that is also called as Rab proteins geranylgeranyltransferase component A 1. This subunit is a substrate-binding subunit of the Rab geranylgeranyl transferase (RGGT) holoenzyme. It binds unprenylated Rab proteins and presents them to the catalytic component B of Rab-GGTase. Alternatively, the subunit encoded by this gene first binds to RGGT, and this complex then binds and prenylates Rab proteins. These Rab proteins are small GTPases that function in regulating vesicular membrane traffic. Mutations in this gene can cause choroideremia, also referred to as tapetochoroidal dystrophy (TCD), that is characterized by progressive dystrophy of the choroid, retinal pigment epithelium and retina.

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.

General description

The gene CHM (choroideremia) is mapped to human chromosome Xq21.2. It encodes a 653 amino acid protein. It contains 15 exons spanning a length of 150kb.
