About MGAT4B

Cytogenetic location: 5q35.3 Genomic coordinates (GRCh38): 5:179,797,597-179,806,866 (from NCBI)

This gene has 23 transcripts (splice variants), 1 gene allele, 212 orthologues and 3 paralogues. Ubiquitous expression in small intestine (RPKM 64.0), duodenum (RPKM 63.6) and 24 other tissues.

Summary

This gene encodes a key glycosyltransferase that regulates the formation of tri- and multiantennary branching structures in the Golgi apparatus. The encoded protein, in addition to the related isoenzyme A, catalyzes the transfer of N-acetylglucosamine (GlcNAc) from UDP-GlcNAc in a beta-1,4 linkage to the Man-alpha-1,3-Man-beta-1,4-GlcNAc arm of R-Man-alpha-1,6(GlcNAc-beta-1,2-Man-alpha-1,3)Man-beta-1,4-GlcNAc-beta-1,4-GlcNAc-beta-1-Asn. The encoded protein may play a role in regulating the availability of serum glycoproteins, oncogenesis, and differentiation. [provided by RefSeq, Jul 2008]
