Galnt1 Gene Summary [Mouse]
Enables polypeptide N-acetylgalactosaminyltransferase activity. Acts upstream of or within protein O-linked glycosylation. Predicted to be located in perinuclear region of cytoplasm. Predicted to be active in Golgi apparatus. Is expressed in several structures, including alimentary system; brain; respiratory system; sensory organ; and skeleton. Used to study heart valve disease. Orthologous to human GALNT1 (polypeptide N-acetylgalactosaminyltransferase 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Galnt1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
