About B4GALNT2

Cytogenetic location: 17q21.32 Genomic coordinates (GRCh38): 17:49,120,344-49,176,840 (from NCBI)

This gene has 3 transcripts (splice variants), 202 orthologues, 1 paralogue and is associated with 1 phenotype. Biased expression in colon (RPKM 11.5), kidney (RPKM 5.5) and 4 other tissues.

Summary

B4GALNT2 catalyzes the last step in the biosynthesis of the human Sd(a) antigen through the addition of an N-acetylgalactosamine residue via a beta-1,4 linkage to a subterminal galactose residue substituted with an alpha-2,3-linked sialic acid. B4GALNT2 also catalyzes the last step in the biosynthesis of the Cad antigen (Montiel et al., 2003 [PubMed 12678917]).[supplied by OMIM, Mar 2008]
