Cysteine protease


Locus: CELE_ZK792.8


Wormbase description: atg-4.2 encodes a putative cysteine protease orthologous to the autophagic budding yeast protein Apg4p, and to human ATG4C (OMIM:611339) and ATG4D (OMIM:611340); ATG-4.2 is paralogous to ATG-4.1 and to human ATG4A and ATG4B; unlike C. elegans orthologs of other yeast autophagic proteins, ATG-4.2 is not required for normal dauer formation, and it has no obvious functions in mass RNAi assays.

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.
