Protein Structure

UniProt Annotation

Function

Transfers 1,4-N-acetylgalactosamine (GalNAc) from UDP- GalNAc to the non-reducing end of glucuronic acid (GlcUA). Required for addition of the first GalNAc to the core tetrasaccharide linker and for elongation of chondroitin chains. Important role in chondroitin chain biosynthesis in cartilage. {ECO:0000269PubMed:17145758}.

Subcellular Localization

Golgi apparatus, Golgi stack membrane {ECO:0000305}; Single-pass type II membrane protein {ECO:0000305}.
