Background:

Growth differentiation factor 2 (GDF2) also known as bone morphogenetic protein 9 (BMP-9) is a protein that in humans is encoded by the GDF2 gene. GDF2 belongs to the transforming growth factor beta superfamily. GDF2 has a role in inducing and maintaining the ability of embryonic basal forebrain cholinergic neurons (BFCN) to respond to a neurotransmitter called acetylcholine; BFCN are important for the processes of learning, memory and attention. GDF2 is also important for the maturation of BFCN. Another role of GDF2 has been recently suggested. GDF2 is a potent inducer of hepcidin (a cationic peptide that has antimicrobial properties) in liver cells (hepatocytes) and can regulate iron metabolism. The physiological receptor of GDF2 is activin receptor-like kinase 1, ALK1 (also called ACVRL1), an endothelial-specific type I receptor of the TGF-beta receptor family. Endoglin, a type I membrane glycoprotein that forms the TGF-beta receptor complex, is a co-receptor of ALK1 for GDF2/BMP-9 binding.
