EXTL2

Exostosin-like 2 is a protein that in humans is encoded by the EXTL2 gene. EXTL2                       Glycosyltransferase is required for the biosynthesis of heparan-sulfate and responsible for the alternating addition of beta-1-4-linked glucuronic acid (GlcA) and alpha-1-4-linked N-acetylglucosamine (GlcNAc) units to nascent heparan sulfate chains.
