Proteasomal-RNAi treatments elicited a dramatic shortening of lifespan in wild-type animals as well as in long-lived daf-2/IIS-receptor mutants, and a glp-1(e2141ts) mutant, whose lifespan is extended by germ cell loss
Double mutant daf-2(mu150);pas-6(RNAi) has a lifespan of 13.5 days, while single mutant daf-2(mu150) has a lifespan of 34.2 days, single mutant pas-6(RNAi) has a lifespan of 14.1 days and wild type has a lifespan of 20.7 days.

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.
Proteasome subunit alpha type-1
Locus: CELE_CD4.6
Wormbase description: pas-6 encodes a type 1 alpha subunit of the 26S proteasome's 20S protease core particle (CP); PAS-6 is required for embryonic, larval, and germline development and by homology, is predicted to comprise the outer rings of the proteasome and to play a role in selective degradation of ubiquitinated proteins during development; in vitro, PAS-6 interacts with BRP-1, a glutamine/asparagine (Q/N)-rich domain-containing protein conserved amongst nematodes, and with other members of the proteasome.
