Psychiatry related information on eat-2

Mutations in eat-2 and eat-18 cause the same defect in C. elegans feeding behavior: the pharynx is unable to pump rapidly in the presence of food [1].

High impact information on eat-2

While eat-2 appears to be required specifically for MC neurotransmission, eat-18 also appears to be required for the function of other nicotinic receptors in the pharynx [1].
eat-2 and eat-18 are required for nicotinic neurotransmission in the Caenorhabditis elegans pharynx [1].
Axenic culture also caused higher activities of the antioxidant enzymes superoxide dismutase and catalase, and led to increased resistance to high temperature, which was further exacerbated by mutation in eat-2 [2].
Metabolic rate was not reduced when we fed wild-type worms reduced food and was up-regulated in the eat-2 mutants in liquid culture, as assessed by oxygen consumption rate and heat production [3].
Conversely, aak-2 was not required for lifespan extension in mutants lacking germline stem cells (glp-1) or mutants of the eating response (eat-2) [4].
