Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables glucuronosyl-N-acetylgalactosaminyl-proteoglycan 4-beta-N-acetylgalactosaminyltransferase activity. Involved in chondroitin sulfate biosynthetic process. Acts upstream of or within chondroitin sulfate metabolic process; extracellular matrix organization; and skeletal system development. Is active in Golgi apparatus. Is expressed in several structures, including alimentary system; genitourinary system; limb; nervous system; and sensory organ. Orthologous to human CSGALNACT1 (chondroitin sulfate N-acetylgalactosaminyltransferase 1).
