The CRTC-1/CREB Module Functions Downstream of AMPK and Calcineurin to Regulate Life Span in Worms
(A) In the presence of high nutrients, AMPK is inactivated whereas calcineurin is activated. CRTC-1 is dephosphorylated and translocates into the nucleus, where it binds to CREB to upregulate CREB-dependent target gene expression.
(B) Low nutrients activate AMPK. Activated AMPK directly phosphorylates CRTC-1 at two conserved sites, resulting in binding and CRTC-1 sequestration in the cytoplasm. The inactivation of the CRTC-1/CREB module elicits the indirect upregulation of ER stress genes, which may contribute to life span extension.
