Human/Mouse/Rat Activin A beta A subunit Biotinylated Antibody Summary

Species Reactivity
Human, Mouse, Rat
Specificity
Detects human Activin A in direct ELISAs. Recognizes proteins containing the precursor or mature beta A subunits. The amino acid sequences of mature beta A subunits from human, mouse, and rat are identical. Therefore, this antibody will also detect the mature beta A subunits from mouse and rat.

Background: Activin A

Activin and Inhibin are members of the TGF-beta superfamily of cytokines and are involved in a wide range of biological processes including tissue morphogenesis and repair, fibrosis, inflammation, neural development, hematopoiesis, reproductive system function, and carcinogenesis (1-7). Activin and Inhibin are produced as precursor proteins. Their amino terminal propeptides are proteolytically cleaved and facilitate formation of disulfide-linked dimers of the bioactive proteins (8, 9). Activins are nonglycosylated homodimers or heterodimers of various beta subunits ( beta A, beta B, beta C, and beta E in mammals), while Inhibins are heterodimers of a unique alpha subunit and one of the beta subunits. Activin A is a widely expressed homodimer of two beta A chains. The beta A subunit can also heterodimerize with a beta B or beta C subunit to form Activin AB and Activin AC, respectively (10). The 14 kDa mature human beta A chain shares 100% amino acid sequence identity with bovine, feline, mouse, porcine, and rat beta A. Activin A exerts its biological activities by binding to the type 2 serine/threonine kinase Activin RIIA which then noncovalently associates with the type 1 serine/threonine kinase Activin RIB/ALK-4 (7, 11). Signaling through this receptor complex leads to Smad activation and regulation of activin-responsive gene transcription (7, 11). The bioactivity of Activin A is regulated by a variety of mechanisms (11). BAMBI, Betaglycan, and Cripto are cell-associated molecules that function as decoy receptors or limit the ability of Activin A to induce receptor complex assembly (12-14). The intracellular formation of Activin A can be prevented by the incorporation of the beta A subunit into Activin AC or Inhibin A (3, 10). And the bioavailability of Activin A is restricted by its incorporation into inactive complexes with alpha 2-Macroglobulin, Follistatin, and FLRG (15, 16).
