Fibronectin Type III Domain Containing Protein 9 (FNDC9)

FNDC9 Contains 1 fibronectin type-III domain.Fibronectins are multi-domain glycoproteins found in a soluble form in plasma, and in an insoluble form in loose connective tissue and basement membranes. They contain multiple copies of 3 repeat regions, which bind to a variety of substances including heparin, collagen, DNA, actin, fibrin and fibronectin receptors on cell surfaces.The Fibronectin type III domain is an evolutionary conserved protein domain that is widely found in animal proteins. The fibronectin protein in which this domain was first identified contains 16 copies of this domain. The domain is about 100 amino acids long and possesses a beta sandwich structure. Fibronectin domains are found in a wide variety of extracellular proteins. They are widely distributed in animal species, but also found more sporadically in yeast, plant and bacterial proteins.
