About MGAT4A

Cytogenetic location: 2q11.2 Genomic coordinates (GRCh38): 2:98,619,106-98,731,132 (from NCBI)

This gene has 9 transcripts (splice variants), 212 orthologues and 3 paralogues. Broad expression in small intestine (RPKM 18.3), colon (RPKM 13.7) 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 B, 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]
