B3GNTL1 (Beta-1,3-N-Acetylglucosaminyltransferase Like 1): B3GNTL1 is an enzyme involved in the biosynthesis of complex carbohydrates, specifically contributing to the formation of glycosaminoglycans, which are key components of the extracellular matrix. These enzymes play important roles in cell communication, signaling, and maintaining structural integrity. Although the full biological functions of B3GNTL1 are still being studied, disruptions in glycosaminoglycan synthesis can impact development and are linked to conditions such as cancer and congenital disorders.
