Recombinant human Activin AB, Active, His-tagged

Cat.No.: INHBA&INHBB-1544H
Product Overview: Recombinant Activin AB is a disulphide linked heterodimer of subunits βA / βB . βA Single chain, containing 116 aa (13.7 kDa) and βB single chain, 123 amino residues (14kDa). Recombinant human Activin AB contains a His-tag at the N-terminal end.
Description: Activins are homodimers or heterodimers of the various β subunit isoforms, belonging to the TGFβ family. Mature Activin AB has two chains of 116 and 123 amino acids residues (βA-βB). Activin exhibits a wide range of biological activities, including mesoderm induction, neural cell differentiation, bone remodelling, haematopoiesis, and reproductive physiology. Activins plays a key role in the production and regulation of hormones such as FSH, LH, GnRH and ACTH. Inhibins /Activins are proteins that are formed by the dimerization of two subunits, i. e. an α with either βA –inhibin A- or βB - inhibin B. The subunits βA and βB can also form homodimers or heterodimers calleds activins: Activin A (βAβA), Activin B (βBβB) and Activin AB (βAβB). The activin gene family comprises the additional, but poorly characterized members activin βC, βD, and βE.As with other members of the super-family, Activins interact with two types of cell surface trans-membrane receptors (Types I and II) which have intrinsic serine/threonine kinase activities in their cytoplasmic domains, Activin type 1 receptors, ACVR1, ACVR1B, ACVR1C and Activin type 2 receptors, ACVR2A, ACVR2B.The development of assays distinguishing between different forms of activins and inhibins, along with knock-in and knock-out models, have provided evidence that the betaA- and betaB-subunits have independent and separate roles physiologically. Additionally, evaluation of ligand-receptor interactions indicates significant differences in receptor affinity between activin isoforms, as well as between inhibin isoforms.
