WebOct 10, 2024 · HFE2 (encoding hemojuvelin, also known as HJV) can act as a BMP coreceptor to enhance hepcidin expression by activating BMP signaling [7,8]. Indeed, HFE2 overexpression significantly increased human and mouse hepcidin promoter activities. However, these activities were reduced to control levels following co-transfection with … WebJan 30, 2007 · Hemojuvelin (HJV) positively modulates the iron regulator hepcidin, and its mutations are the major cause of juvenile hemochromatosis (JH), a recessive disease leading to iron overload. Defective HJV reduces hepcidin up-regulation both in humans and in Hjv -deficient mice.
Hemojuvelin (HJV), also known as repulsive guidance molecule C (RGMc) or hemochromatosis type 2 protein (HFE2), is a membrane-bound and soluble protein in mammals that is responsible for the iron overload condition known as juvenile hemochromatosis in humans, a severe form of … See more For many years the signal transduction pathways that regulate systemic iron homeostasis have been unknown.
