EC Tree
IUBMB Comments
Terminal N-acetyl-beta-D-glucosaminyl residues in polysaccharides, glycoproteins and glycopeptides can act as acceptor. High activity is shown towards such residues in branched-chain polysaccharides when these are linked by beta-1,6-links to galactose residues; lower activity towards residues linked to galactose by beta-1,3-links. A component of EC 2.4.1.22 (lactose synthase).

beta-1,4-GalT-I mRNA is significant increased 2 h after lipopolysaccharide stimulation with 0.001 mg/ml
-
CDK11p58 and beta-1,4-GalT-I are induced in lipopolysaccharide-challenged rat primary astrocytes in a affinis dose- and time-dependent manner. CDK11p58 regulates the expression of beta-1,4-GalT-I by interacting with it. The expression of beta-1,4-GalT-I increases, and astrocyte activation enhances due to the overexpression of CDK11p58
-
mRNA and protein expression of beta1,4-GalT-I increases in synovial tissue of a collagen-induced rat model of rheumatoid arthritis compared with the normal group at 10d and 15d after collagen-induced
