PFAM accession number:PF05679
Interpro abstract (IPR008428):

This family represents Chondroitin N-acetylgalactosaminyltransferase. Proteins have a type II transmembrane topology. The enzyme is involved in the biosynthetic initiation and elongation of chondroitin sulphate and is the key enzyme responsible for the selective chain assembly of chondroitin/dermatan sulphate on the linkage region tetrasaccharide common to various proteoglycans containing chondroitin/dermatan sulphate or heparin/heparan sulphate chains [ (PUBMED:11788602) (PUBMED:11514575) ].

GO component:Golgi cisterna membrane (GO:0032580)
GO function:acetylgalactosaminyltransferase activity (GO:0008376)
