egl-4

Gene
egl-4
Protein
cGMP-dependent protein kinase egl-4
Organism
Caenorhabditis elegans
Length
780 amino acids
Function
Promotes chemoreceptor gene expression in response to increased cGMP levels by antagonizing the gene repression functions of the class II HDAC hda-4 and the mef-2 transcription factor (PubMed:18832350). Regulates gene expression via recruitment of a histone deacetylase complex containing hda-2, saeg-1 and saeg-2 (PubMed:21573134). Represses body size and lifespan through the dbl-1 and insulin pathways, respectively (PubMed:12571101, PubMed:15330854, PubMed:26434723). May also signal through daf-3 and/or daf-5. Role in egg-laying, dauer formation and motility (PubMed:12571101, PubMed:11181837, PubMed:21573134). Regulates behavioral responses to various chemosensory stimuli in sensory neurons (PubMed:10978280, PubMed:22319638, PubMed:23874221, PubMed:26434723). Required for the initiation of long term adaptation to prolonged odor exposure which results in a decrease in odor seeking behavior (PubMed:12495623, PubMed:20220099, PubMed:26434723). May regulate this process by phosphorylating tax-2, a subunit of cyclic nucleotide-gated channel tax-2/tax-4 (PubMed:12495623). In ASH sensory neurons, negatively regulates avoidance behavior to some bitter tastants, such as quinine, probably by phosphorylating rgs-2 and rgs-3 which are 2 regulator of G-protein signaling proteins (PubMed:23874221). In AWB sensory neurons, involved in avoidance behavior to some repellent odors (PubMed:23954825). In ASE left (ASEL) sensory neuron, involved in the sensing of environmental alkalinity downstream of receptor-type guanylate cyclase gcy-14 (PubMed:23664973). In sensory neurons, involved in the signaling pathway downstream of insulin, TGF-beta and receptor-type guanylate cyclase responsible for inducing quiescence after food intake (PubMed:18316030). Might play a role in aversive olfactory learning in AWC neurons when an odor is associated with food deprivation, depending on the ins-1/age-1 signal from the AIA to the AWC neurons (PubMed:27383131). Probably by regulating neuronal transmission downstream of lin-3 and receptor lin-23 and phospholipase plc-3 in ALA neurons, involved in the decrease in locomotion during the quiescent state that precedes each larval molt (PubMed:17891142).
