EXT1 (Exostosin-1) is an enzyme. In the public catalogues the evidence so far is association rather than a proven role. Tied to Sarcomas, Breast cancer, Ovarian cancer and 2 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Glycosyltransferase forming with EXT2 the heterodimeric heparan sulfate polymerase which catalyses the elongation of the heparan sulfate glycan backbone. Glycan backbone extension consists in the alternating transfer of (1->4)-beta-D-GlcA and (1->4)-alpha-D-GlcNAc residues from their respective UDP-sugar donors. Both EXT1 and EXT2 are required for the full activity of the polymerase since EXT1 bears the N-acetylglucosaminyl-proteoglycan 4-beta-glucuronosyltransferase activity within the complex while EXT2 carries the glucuronosyl-N-acetylglucosaminyl-proteoglycan 4-alpha-N-acetylglucosaminyltransferase activity. Heparan sulfate proteoglycans are ubiquitous components of the extracellular matrix and play an important role in tissue homeostasis and signalling. Location: Golgi apparatus membrane; Golgi apparatus, cis-Golgi network membrane; Endoplasmic reticulum membrane (UniProt). Locus 8q24.11 (HGNC).
