Acts as a sensor that couples lifespan to information about energy levels and insulin-like signals. Role in motility and response to oxidative stress. Involved in the establishment of germline stem cell (GSC) quiescence during dauer development. Plays a role in axon regrowth after axotomy in PLM neurons. Plays a role in the maintenance of glycogen stores which are necessary for resistance to hyperosmotic stress. Plays a role in the regulation of flp-7 secretion from ASI neurons. Keeps the CREB-regulated transcription coactivator 1 homolog crtc-1 inactive which in turn inhibits flp-7 secretion. Following serotonin signaling, derepresses crtc-1 which stimulates flp-7 secretion and subsequent body fat loss
