Predicted to enable UDP-galactose:beta-N-acetylglucosamine beta-1,3-galactosyltransferase activity and galactosylxylosylprotein 3-beta-galactosyltransferase activity. Predicted to be involved in glycosaminoglycan biosynthetic process and proteoglycan biosynthetic process. Predicted to be located in Golgi medial cisterna. Predicted to be active in Golgi membrane. Human ortholog(s) of this gene implicated in Ehlers-Danlos syndrome spondylodysplastic type 2 and spondyloepimetaphyseal dysplasia with joint laxity type 1. Orthologous to human B3GALT6 (beta-1,3-galactosyltransferase 6). [provided by Alliance of Genome Resources, Apr 2022]
