Purified recombinant Human GDF3 protein Expression System: E.coli Bioactivity: Determined by its ability to inhibit induced alkaline phosphatase production by ATDC-5 chondrogenic cells. The ED50 for this effect is 100-150 ng/mL.
GDF-3 is a member of the TGF beta superfamily of growth and differentiation factors, and is highly homologous to GDF-9. Unlike most TGF beta family members, GDF-3 and GDF-9 are not disulfide-linked dimers. GDF-3 is expressed in adult bone marrow, spleen, thymus, and adipose tissue. The expression of GDF-3 is upregulated in high-fat-fed wild-type FABP4/aP2 null mice and was associated with obesity, but not with the related hyperglycemia/hyperinsulinemia which characterizes Type 2 diabetes. Alternative Names: GDF 3 protein, GDF-3 protein, GDF-3, GDF3, Growth/Differentiation Factor-3 protein, GDF-3 protein, GDF 3
