Galnt3 Gene Summary [Mouse]
Enables polypeptide N-acetylgalactosaminyltransferase activity. Involved in protein O-linked glycosylation. Acts upstream of or within several processes, including chondroitin sulfate proteoglycan biosynthetic process; limb development; and skeletal system development. 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; limb; respiratory system; and sensory organ. Used to study hyperphosphatemic familial tumoral calcinosis. Orthologous to human GALNT3 (polypeptide N-acetylgalactosaminyltransferase 3). [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 Galnt3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
