Protein Structure
UniProt Annotation
Function Catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D- galactosamine residue to a serine or threonine residue on the protein receptor. Has a highest activity toward EA2 peptide substrate and a much lower activity with EPO-T, Muc2, Muc1a, Muc1b.
Subcellular Localization Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}.
Disease Associations
Tissue Specificity Highly expressed in sublingual gland, stomach, colon, small intestine and cervix. Expressed at intermediate levels in kidney, ovary, lung and uterus. Weakly expressed in spleen, liver, heart and brain. Not expressed in submandibular and parotid glands, skeletal muscle and testis. {ECO:0000269PubMed:9153242}.
