Summary: Enables alpha-1,6-mannosylglycoprotein 2-beta-N-acetylglucosaminyltransferase activity. Acts upstream of or within protein N-linked glycosylation via asparagine. Predicted to be located in Golgi apparatus. Predicted to be active in Golgi membrane. Is expressed in several structures, including alimentary system; cranium; integumental system; sensory organ; and telencephalon. Used to study congenital disorder of glycosylation type IIa. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type IIa. Orthologous to human MGAT2 (alpha-1,6-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase).

What's a GeneRIF?

the CD11c promoter was unexpectedly active and triggered Mgat2 deletion within multiple hematopoietic lineages, showed remarkably poor penetrance within native DC populations, and produced almost undetectable levels of green fluorescent protein signal. These findings show that the CD11c promoter is not DC-specific, and extreme care should be taken in the interpretation of data using any mouse created using the CD11c-CRE
Title: Dendritic cell-specific Mgat2 knockout mice show antigen presentation defects but reveal an unexpected CD11c expression pattern.
when the C-terminal cysteine (C334) was mutated, MGAT activity was actually higher than that of wild-type FL-MGAT2. Lastly, we determined that both transmembrane domains of MGAT2 are important for its ER localization, and that MGAT2 is present in mitochondrial-associated membranes.

The use of 1-oleoyl-glycerol-d5 and (U13)C-TG oil followed by LC/ESI/MS/MS detection of stable-isotopic labeled DAG, TG, or glycerol provides a wide range of applications to study pathophysiological regulation of the monoacylglycerol pathway and MGAT2 activity.

Title: MGAT2 deficiency and vertical sleeve gastrectomy have independent metabolic effects in the mouse.
The results suggest that MGAT2 has a pivotal role in lipid metabolism in the small intestine, and the inhibition of MGAT2 activity may be a promising strategy for the treatment of obesity-related metabolic disorders.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
