Cholesterol 7-desaturase; Catalyzes the production of 7-dehydrocholesterol (7-DHC) by the desaturation of the C7-C8 single bond of cholesterol. This reaction is the first step in the synthesis of the steroid hormone Delta(7)- dafachronic acid. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth.

Cytochrome P450 daf-9; Sterol hydroxylase that catalyzes the successive oxidization of the side chains of the 3-keto steroids 4-cholesten-3-one and lathosterone to form their carboxylic acid derivatives Delta(4)- dafachronic acid and Delta(7)-dafachronic acid respectively. Dafachronic acids bind directly to the nuclear hormone receptor (NHR) daf-12, suppressing dauer formation and inducing reproductive growth. In a non-cell autonomous manner, negatively regulates body wall muscle arm extensions to motor neurons probably by preventing daf-12 isoform b activation. May be involved in ther [...]

Forkhead box protein O; Forkhead-type transcription factor. Binds to the promoters of genes that contain the daf-16 binding element (DBE), TTGTTTAC, in their regulatory region. Functions in the Insulin/IGF-1-like signaling (IIS) mediated pathway which affects lipogenesis, lifespan, starvation survival, heat shock and oxidative stress responses, and dauer formation. Longevity signaling predominantly arises from expression in the intestine. Daf-16 transcriptional activity is negatively regulated by cytoplasmic sequestration by association with ftt-2. Inhibition is required for the carbon [...]

BHLH domain-containing protein.

Mediator of RNA polymerase II transcription subunit 15; Component of the Mediator complex, a coactivator involved in regulated gene transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene- specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors (By similarity). Require [...]

Multidrug resistance protein pgp-3; Mediates ATP-dependent export of organic anions and xenobiotics from the cytoplasm. Hydrolyzes ATP with low efficiency (By similarity); Belongs to the ABC transporter superfamily. ABCB family. Multidrug resistance exporter (TC 3.A.1.201) subfamily.

Insulin-like receptor subunit alpha; Insulin receptor-like tyrosine kinase which regulates metabolism, controls longevity and prevents developmental arrest at the dauer stage. Binding of INS family members may either stimulate, or antagonize, association of the receptor with downstream mediators such as pdk-1 and age-1. Required for germline progenitor proliferation during larval development. Required for the response to environmental stimuli such as food, pheromone, and temperature. Negatively regulates resistance to UV and oxidative stress. Role in immune function and pathogen resist [...]

Serine/threonine-protein kinase flr-4; Probable serine-threonine protein kinase involved in the control of defecation rhythms. Required to increase the length of defecation cycle period. Acts in a cell-functional rather than developmental aspect in the regulation of defecation rhythms.

Aryl hydrocarbon receptor protein 1; Probable ligand-activated transcriptional activator. Acts as a transcriptional regulator in GABAergic motor neuron cell fate specification and development. Promotes cell-type-specific expression of guanylate cyclase genes that have key roles in aggregation behavior and hyperoxia avoidance. Has no role in carbon dioxide avoidance.
