Product Name | Recombinant Human Activin A protein |
Description | Human recombinant protein expressed in Nicotiana benthamiana. It is produced by transient expression in non-transgenic plants. This product contains no animal-derived components or impurities. Animal Free product. Activins are homodimers or heterodimers of the various beta subunit isoforms, belonging to the TGFbeta family. Mature Activin A has two 116 amino acids residues betaA subunits (betaA-betaA). 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. Cells known to express Activin A include fibroblasts, endothelial cells, hepatocytes, vascular smooth muscle cells, macrophages, keratinocytes, osteoclasts, bone marrow monocytes, prostatic epithelium, neurons, chondrocytes, osteoblasts, Leydig cells, Sertoli cells, and ovarian granulosa cells. 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 biological activity of Activin A can be neutralized by inhibins and by the diffusible TGF-B antagonist, Follistatin. Recombinant human Activin A is a polypeptide chain containing 116 amino acids (311- 426 P08476 INHBA_HUMAN) and a His-tag at the N-terminal end. Several forms are observed with different predicted molecular masses such as monomer (13.7 kDa), dimmer ( 27.4 kDa) and multimeric forms. Purity >97% by SDS-PAGE gel |
