Exostosin-Like 2/EXTL2 Protein(N-6His) (recombinant mouse)

Protein Construction: Recombinant Mouse Exostosin-like 2 is produced by our Mammalian expression system and the target gene encoding Asn43-Met330 is expressed with a 6His tag at the N-terminus. Sequence: Asn43-Met330. Fusion tag: N-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 35kDa. Protein function: Exostosin-like 2 (EXTL2) is a member of the exostosin (EXT)-related family which contains five members: EXT1, EXT2, EXTL1, EXTL2, and EXTL3. Studies have shown that EXT gene family members have the activities of heparan sulfate-synthesizing glycosyltransferases. EXT1 and EXT2, which have been identified as causal genes for hereditary multiple exostoses, have HS-GlcAT-II and GlcNAcT-II activities. EXTL1 has GlcNAcT-II activity and EXTL3 has GlcNAcT-I and -II activities. EXTL2 has GlcNAcT-I and N-acetylgalactosaminyltransferase activities, and transfers a GlcNAc residue to the tetrasaccharide linkage region when this region is phosphorylated by a xylose kinase 1 (FAM20B) and thereby terminate chain elongation. In mice, lack of EXTL2 causes glycosaminoglycan (GAG) overproduction and structural changes of GAGs associated with pathological processes. Protein function: Glycosyltransferase 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.
