Gene Information

human ... ATRX(546)

General description

ATRX (α-thalassemia/mental retardation syndrome X-linked) is encoded by the gene mapped to human chromosome Xq21.1. The encoded protein belongs to SWI/SNF (SWItch/sucrose non-fermentable) family of chromatin remodeling proteins.


alpha thalassemia/mental retardation syndrome X-linked, recombinant protein epitope signature tag (PrEST)



Biochem/physiol Actions

ATRX (α-thalassemia/mental retardation syndrome X-linked) is involved in the H3.3-ATRX-DAXX chromatin-remodeling pathway. It plays a vital role in assimilation of the histone variant H3.3 at pericentric heterochromatin and at telomeres, as well as at several transcription factor binding sites. Mutation in the gene has been observed in various types of gliomas. Thus, this protein can be considered as a potential biomarker for gliomas. In addition, aberrations in the gene expression leads to characteristic developmental abnormalities, such as severe mental retardation, facial dysmorphism, urogenital abnormalities and α-thalassemia.

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.


Corresponding Antigen APREST74299.

Physical form

Phospate buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
