ogt-1 encodes an ortholog of O-linked N-acetylglucosamine (O-GlcNAc) transferase (OGT; OMIM:300255) with 12 N-terminal tetratricopeptide (TPR) domains (generally thought to enable protein-protein interactions) and a C-terminal putative catalytic domain; although loss of ogt-1 activity has no effect on overall viability or fertility, ogt-1 mutations result in alterations in macronutrient storage and can suppress constitutive dauer formation in daf-2 mutants suggesting that, in C. elegans, ogt-1 may play a regulatory role in nutrient sensing and insulin-like signaling pathways; OGT-1 is expressed in embryos, where it exhibits nuclear and punctate perinuclear localization.
Enables protein N-acetylglucosaminyltransferase activity; protein O-acetylglucosaminyltransferase activity; and protein serine/threonine phosphatase activity. Involved in several processes, including dauer larval development; glycogen metabolic process; and lipid storage. Located in nucleus and perinuclear region of cytoplasm. Expressed in several structures, including hypodermal cell; intestine; neurons; and somatic cell. Used to study type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in aortic valve stenosis and non-syndromic X-linked intellectual disability 106. Is an ortholog of human OGT (O-linked N-acetylglucosamine (GlcNAc) transferase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
