Summary: Predicted to enable beta-1,3-galactosyl-O-glycosyl-glycoprotein beta-1,3-N-acetylglucosaminyltransferase activity and manganese ion binding activity. Acts upstream of or within several processes, including nervous system development; protein O-linked mannosylation; and reactive gliosis. Predicted to be located in membrane. Predicted to be active in Golgi membrane. Is expressed in several structures, including alimentary system; genitourinary system; liver; nervous system; and respiratory system. Used to study Walker-Warburg syndrome and muscular dystrophy-dystroglycanopathy type B1. Human ortholog(s) of this gene implicated in lissencephaly; muscular dystrophy (multiple); and retinitis pigmentosa.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
