| ncRNA Symbol: | MGAT4B | | Full Name: | alpha-1,3-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase B | | Category: | mRNA | | Synonyms: | GNT-IV|GNT-IVB | | Chromosome: | chr5 | | Strand: | - | | Coordinate: | | Start Site(bp): | 179797597 | End Site(bp): | 179806952 | | | Gene 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] | | External Links: | |
