B4GALNT1 - beta-1,4-N-acetyl-galactosaminyltransferase 1 Gene
Also Known as GALGT; SPG26; GALNACT; GalNAc-T
Species: Homo sapiens
About B4GALNT1
This gene has 16 transcripts (splice variants), 265 orthologues, 1 paralogue and is associated with 2 phenotypes. Broad expression in brain (RPKM 8.2), endometrium (RPKM 1.8) and 16 other tissues.
Summary
GM2 and GD2 gangliosides are sialic acid-containing glycosphingolipids. GalNAc-T is the enzyme involved in the biosynthesis of G(M2) and G(D2) glycosphingolipids. GalNAc-T catalyzes the transfer of GalNAc into G(M3) and G(D3) by a beta-1,4 linkage, resulting in the synthesis of G(M2) and G(D2), respectively. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2013]
