Predicted to enable hexosyltransferase activity. Predicted to be involved in chondroitin sulfate proteoglycan biosynthetic process and nucleotide-sugar metabolic process. Predicted to act upstream of or within chondroitin sulfate metabolic process; extracellular matrix organization; and skeletal system development. Predicted to be located in Golgi cisterna membrane. Predicted to be integral component of membrane. Orthologous to human CSGALNACT1 (chondroitin sulfate N-acetylgalactosaminyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
