5'-AMP-activated protein kinase catalytic subunit alpha-2


Locus: CELE_T01C8.1


Wormbase description: aak-2 encodes one of two C. elegans homologs of the catalytic alpha subunit of AMP-activated protein kinases (AMPKs); in C. elegans, aak-2 functions downstream of environmental stressors, energy level signals (AMP:ATP ratio), and daf-2-mediated insulin signaling to positively regulate adult lifespan; in regulating lifespan, aak-2 likely acts in parallel with daf-16/FOXO; aak-2 activity is also required for dauer formation in daf-2 mutant animals at high temperature in a manner independent of the AMP:ATP ratio; in the germline, aak-2 functions downstream of daf-2 and daf-7, and in parallel to par-4 and aak-1, to negatively regulate germline proliferation during dauer development; in vitro, AAK-2 exhibits AMP-enhanced kinase activity against a known AMPK substrate, the SAMS peptide.

Initiation Factor 4G (eIF4G) family


Locus: CELE_M110.4


Wormbase description: ifg-1 encodes, by alternative splicing, two orthologs of the translation initiation factor 4F, ribosome/mRNA-bridging subunit (eIF-4G); by homology, IFG-1 is predicted to function in poly(A) tail-dependent translation initiation; loss of ifg-1 activity in adult animals extends lifespan.
