Enables galactosylxylosylprotein 3-beta-galactosyltransferase activity. Involved in glycosaminoglycan biosynthetic process. Located in Golgi medial cisterna. Is active in Golgi apparatus. Is expressed in medial ganglionic eminence. 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, Jul 2025]
Predicted to enable N-acetyllactosaminide beta-1,3-N-acetylglucosaminyltransferase activity. Acts upstream of or within several processes, including axon guidance; cellular response to leukemia inhibitory factor; and sensory perception of smell. Predicted to be active in Golgi membrane. Is expressed
in several structures, including alimentary system; brain; genitourinary system; immune system; and nose. Orthologous to human B3GNT2 (UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 2). [provided by Alliance of Genome Resources, Apr 2025]
