Summary: Enables AMP-activated protein kinase activity. Involved in several processes, including determination of adult lifespan; nematode pharyngeal pumping; and regulation of protein secretion. Located in axon; cytoplasm; and neuronal cell body. Is expressed in several structures, including body wall musculature; excretory cell; nervous system; pharynx; and reproductive system. Human ortholog(s) of this gene implicated in Huntington's disease; breast cancer; colon cancer; and type 2 diabetes mellitus. Orthologous to human PRKAA1 (protein kinase AMP-activated catalytic subunit alpha 1) and PRKAA2 (protein kinase AMP-activated catalytic subunit alpha 2).

mir-259 functioned in pharynx-intestinal valve and RSKS-1 functioned in pharynx to regulate MWCNTs toxicity. Furthermore, RSKS-1 regulated MWCNTs toxicity by suppressing the function of AAK-2-DAF-16 signaling cascade. Our results will strengthen our understanding the microRNAs mediated protection mechanisms for animals against the toxicity from certain nanomaterials.

he results revealed that RNAi-mediated inactivation of several genes restores gonad elongation, including aak-2, which encodes the catalytic subunit of AMP-activated protein kinase (AMPK). We then generated triple mutant worms for cnnm-1; cnnm-3; aak-2 and confirmed that the aak-2 mutation also suppressed the defective gonadal elongation in cnnm-1; cnnm-3 mutant worms.
