Catalog Numbers: 800-01 is a replacement number for Human 100-43 / Mouse 200-29 / Rat 300-06 (100% sequence identity)

Alternate Names:  Inhibin beta-1, FRP, FSH-releasing protein              

Accession Number: P08476
Description:  Activin A is a member of the transforming growth factor beta (TGF-β) family of proteins and functions to stimulate follicle-stimulating hormone (FSH) secretion.  Activins are produced in many tissue types including the skin, gonads, lungs, and pituitary gland.  Activins interact with receptor type I and type II serine/threonine protein kinases, to activate SMAD signaling and regulate diverse cellular functions, such as cell proliferation, differentiation, wound healing, apoptosis, and metabolism.  Activin A is a homodimer comprised of two activin βA chains.  Cleavage of the N-terminal propeptide renders the Activin protein biologically active.  Human Activin A shares 100% amino acid sequence identity with mouse, rat, porcine, bovine, and feline Activin A proteins.
Source:  Genetically modified E.coli.
Predicted MW: Dimer, 13.1/26.2 kDa (117/234 aa)
Formulation:  Lyophilized from a sterile (0.2 micron) filtered aqueous solution containing 0.1% Trifluoroacetic Acid (TFA)
