Summaries for EXTL1 Gene

Entrez Gene Summary for EXTL1 Gene

  • This gene is a member of the multiple exostoses (EXT) family of glycosyltransferases, which function in the chain polymerization of heparan sulfate and heparin. The encoded protein harbors alpha 1,4- N-acetylglucosaminyltransferase activity, and is involved in chain elongation of heparan sulfate and possibly heparin. [provided by RefSeq, Jul 2008]

GeneCards Summary for EXTL1 Gene
