Beta 1, 3-N-acetylglucosaminyltransferase is essential for the formation of poly-N-acetyllactosamine .
This family includes human Beta3GnTL1 and related eukaryotic proteins. Human Beta3GnTL1 is a putative beta-1,3-N-acetylglucosaminyltransferase. Beta3GnTL1 is expressed at various levels in most of tissues examined. Beta 1, 3-N-acetylglucosaminyltransferase has been found to be essential for the formation of poly-N-acetyllactosamine. Poly-N-acetyllactosamine is a unique carbohydrate composed of N-acetyllactosamine repeats. It is often an important part of cell-type-specific oligosaccharide structures and some functional oligosaccharides. It has been shown that the structure and biosynthesis of poly-N-acetyllactosamine display a dramatic change during development and oncogenesis. Several members of beta-1, 3-N-acetylglucosaminyltransferase have been identified.
