NCIt definition : Exostosin-like 2 (330 aa, 37 kDa) is encoded by the human EXTL2 gene. This protein
plays a role in glycosaminoglycan biosynthesis and heparan sulfate modification.;
NCIt note : A soluble form of exostosin-like 2, which is a result of proteolytic processing, is
found in serum. (UniProt); Exostosin-like 2 is a type II membrane protein glycosyltransferase of the endoplasmic
reticulum that initiates heparan sulfate/heparin biosynthesis by alternating addition
of beta-1-4-linked glucuronic acid (GlcA) and alpha-1-4-linked N-acetylglucosamine
(GlcNAc) units to nascent heparan sulfate and heparin chains.;
