Anti-Exostosin-Like 1 antibodies enable researchers to detect and measure the Exostosin-Like 1 antigen in biological samples. This target is a reported synonym of the EXTL1 gene, which encodes exostosin like glycosyltransferase 1. This protein is known to function in protein glycosylation and skeletal system development, among other biological roles. The human version of Exostosin-Like 1 has a canonical amino acid length of 676 residues and a protein mass of 74.7 kilodaltons. It is reported to be localized in the ER of cells. Other names for this target antigen include EXTL and alpha-N-acetylglucosaminyltransferase II.
