Gene Information

human ... INHA(3623)

General description

The gene INHA (inhibin α chain) is mapped to human chromosome 2q35.


Inhibin alpha chain Precursor recombinant protein epitope signature tag (PrEST)

Biochem/physiol Actions

INHA (inhibin α chain) is a subunit of inhibins. Inhibins are responsible for suppression of FSH (follicle-stimulating hormone) secretion. INHA is down-regulated in prostate cancer. On the other hand, it is up-regulated in ovarian cancer. Polymorphism in INHA promoter is linked with infertility in males. Similarly, INHA promoter polymorphism is linked with risk of idiopathic primary ovarian insufficiency.

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 APREST74078.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

The aim of this study was to investigate whether two polymorphisms in the promoter region of inhibin alpha (INHA) are associated with risk of idiopathic primary ovarian insufficiency (POI) in Korean women, which is a controversial topic. We genotyped the...

Inhibins play important roles in normal gonadal function, including regulation of proliferation, differentiation, and steroidogenesis of Leydig and Sertoli cells via paracrine and autocrine processes. In adult males, circulating inhibin levels are correlated with fertility by regulating the number of...
