N-Acetylgalactosaminyltransferase 4

N-Acetylgalactosaminyltransferase 4 (GALNT4) is a glycosyltransferase capable of inhibiting the activation of ASK1. It functions by directly binding to ASK1, preventing N-terminal dimerization and subsequent phosphorylation. This interaction leads to significant inactivation of downstream JNK/p38 and NF-κB signaling, thereby improving the prognosis of liver surgery.
