B4GALT Antibodies

The B4GALT gene, specifically B4GALT1, is one of the genes that encodes an enzyme known as beta-1,4-galactosyltransferase. This enzyme is involved in the biosynthesis of complex glycoproteins and glycolipids.

Key points about the B4GALT gene:

Gene Name: B4GALT, specifically B4GALT1 for one of the isoforms.

Enzyme: The protein product of the B4GALT gene is beta-1,4-galactosyltransferase, an enzyme responsible for catalyzing the transfer of galactose to the growing carbohydrate chains in glycoproteins and glycolipids.

Glycosylation: B4GALT enzymes are essential for the synthesis of complex carbohydrates in the Golgi apparatus. They play a role in adding galactose residues to sugar chains, contributing to the diversity of glycoprotein and glycolipid structures.

Glycoprotein and Glycolipid Synthesis: B4GALT enzymes participate in the synthesis of various glycoproteins and glycolipids, which are crucial for cell signaling, recognition, and other cellular processes.

Isoforms: There are multiple isoforms of beta-1,4-galactosyltransferase encoded by different B4GALT genes (e.g., B4GALT2, B4GALT3), and they may have tissue-specific expression patterns and substrate preferences.

Disease Associations: Alterations in glycosylation patterns, including those involving beta-1,4-galactosyltransferase, can be associated with various diseases, including certain types of cancer.

Research on B4GALT genes and their products is ongoing, and understanding their roles in glycosylation is essential for unraveling the complexity of cellular processes. Glycosylation is a critical post-translational modification that influences the structure and function of proteins.
