WormMine: Gene WBGene00008205

• WormBase Gene ID: WBGene00008205
• Gene Name: sams-1
• Sequence Name: C49F5.1
• Brief Description: sams-1 encodes an S-adenosyl methionine synthetase; by homology, SAMS-1 is predicted to function as a methyl-group donor in many biochemical reactions; sams-1 expression levels are negatively regulated by dietary restriction (as seen in eat-2 mutant animals), suggesting that increased lifespan due to dietary restriction is due, in part, to reducing the activity of key metabolic enzymes; loss of sams-1 via RNAi can extend adult lifespan.
• Organism: Caenorhabditis elegans
• Automated Description: Enables methionine adenosyltransferase activity. Involved in S-adenosylmethionine biosynthetic process and negative regulation of lipid storage. Predicted to be located in cytosol. Expressed in body wall musculature; dorsal nerve cord; and ventral nerve cord. Used to study lipid metabolism disorder. Human ortholog(s) of this gene implicated in hypermethioninemia and lung cancer. Is an ortholog of human MAT1A (methionine adenosyltransferase 1A) and MAT2A (methionine adenosyltransferase 2A).
