Summary: 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, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
