Neuronal acetylcholine receptor subunit eat-2


Locus: CELE_Y48B6A.4


Wormbase description: eat-2 encodes a ligand-gated ion channel subunit most closely related to the non-alpha-subunits of nicotinic acetylcholine receptors (nAChR); EAT-2 functions postsynaptically in pharyngeal muscle to regulate the rate of pharyngeal pumping; eat-2 is also required for normal life span and defecation; a functional EAT-2::GFP fusion protein localizes to two small dots near the junction of pharyngeal muscles pm4 and pm5, which is the site of the posterior-most MC motor neuron processes and the MC synapse; eat-2 genetically interacts with eat-18, which encodes a predicted novel transmembrane protein expressed in pharyngeal muscle and required for proper function of pharyngeal nicotonic receptors.

Mediator of RNA polymerase II transcription subunit 15


Locus: CELE_R12B2.5


Wormbase description: mdt-15 encodes, by alternative splicing, two isoforms of a Mediator subunit orthologous to human MED15; together with NHR-49 and SBP-1, MDT-15 is required for normal fat accumulation, for expression of fatty acid (FA) desaturase genes (fat-5, fat-6, and fat-7), for normal levels of mono- and polyunsaturated FAs (PUFAs), and for viability, fecundity, mobility, and normally long lifespan; several of these phenotypes can be at least partially suppressed by supplying PUFAs in the food medium; in part through NHR-49, MDT-15 participates in basal and fasting-induced transcription of numerous other metabolic genes, such as gei-7 and acs-2; independently of NHR-49 and SBP-1, MDT-15 ensures appropriate transcriptional response and survival in response to toxins and heavy metals by inducing select detoxification genes encoding such as cdr-1, cyp-35C1, gst-5, mtl-1, mtl-2, ugt-1, ugt-8, and others; mdt-15 is expressed at constant levels from embryos to adulthood, in several head neurons and intestine; MDT-15 binds NHR-49 and NHR-64 in yeast two-hybrid assays, and SBP-1 in GST pull-down assays.
