Descripción

General description

HEXIM1 (hexamethylene bis-acetamide inducible 1) functions as a homdimer and was first recognized in hexamethylene bisacetamide (HMBA) treated vascular smooth muscle cells. It is primarily known as the inhibitor of positive transcription elongation factor b (P-TEFb). This gene is localized to human chromosome 17q21.31.

Immunogen

hexamethylene bis-acetamide inducible 1 recombinant protein epitope signature tag (PrEST)

Application

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.

Biochem/physiol Actions

HEXIM1 (hexamethylene bis-acetamide inducible 1) is a tight regulator of the activity of positive transcription elongation factor b (P-TEFb). This protein interacts with the small P-TEFb complex, which then facilitates the formation of the large, inactive P-TEFb complex. Its interaction with P-TEFb is also responsible for the induction of differentiation of human pluripotent stem cells. Through regulation of P-TEFb, HEXIM1 controls the expression of cyclin D1 in mammary epithelial cells in a 17β-estradiol/estrogen receptor-α-dependent manner. Hexamethylene bisacetamide (HMBA) functions as an antagonist of HEXIM1 and leads to its dissociation from P-TEFb, thus promoting the transcription of HIV (human immunodeficiency virus).

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.
