  • Lifespan change (compared to wild type)

  • Phenotype

    Double mutants of aak-2(ok524) and stronger daf-2 reduction-of-function alleles have shortened lifespans compared with daf-2 single mutants, although they live longer than aak-2(ok524) single mutants. Therefore, aak-2-independent as well as aak-2-dependent mechanisms are required to produce the exceptionally long lifespans of daf-2 mutants.

  • Lifespan comparisons

    Double mutant aak-2(ok524);daf-2(e1368) has a lifespan of 25.1 days, while single mutant aak-2(ok524) has a lifespan of 17.6 days, single mutant daf-2(e1368) has a lifespan of 36.7 days and wild type has a lifespan of 20.0 days.

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.

Insulin-like receptor subunit beta;Receptor protein-tyrosine kinase;hypothetical protein


Locus: CELE_Y55D5A.5


Wormbase description: daf-2 encodes a receptor tyrosine kinase that is the C. elegans insulin/IGF receptor ortholog; DAF-2 activity is required for a number of processes in C. elegans, including embryonic and larval development, formation of the developmentally arrested dauer larval stage (diapause), larval developmental timing, adult longevity, reproduction, fat storage, salt chemotaxis learning, and stress resistance, including response to high temperature, oxidative stress, and bacterial infection; DAF-2 signals through a conserved PI 3-kinase pathway to negatively regulate the activity of DAF-16, a Forkhead-related transcription factor, by inducing its phosphorylation and nuclear exclusion; in addition, DAF-2 negatively regulates the nuclear localization, and hence transcriptional activity, of SKN-1 in intestinal nuclei; amongst the 38 predicted insulin-like molecules in C. elegans, genetic and microarray analyses suggest that at least DAF-28, INS-1, and INS-7 are likely DAF-2 ligands; genetic mosaic and tissue-specific promoter studies indicate that daf-2 can function cell nonautonomously and within multiple cell types to influence dauer formation and adult lifespan, likely by regulating the production of secondary endocrine signals that coordinate growth and longevity throughout the animal; temporal analysis of daf-2 function indicates that daf-2 regulates lifespan, reproduction, and diapause independently, at distinct times during the animal's life cycle.
