F-box/WD repeat-containing protein mec-15 (Mechanosensory abnormality protein 15) |
DISRUPTION PHENOTYPE |
Temperature-sensitive phenotype with defective touch receptor neuron synaptic transmission conferring variable degrees of touch insensitivity amongst individual animals (PubMed:8692859, PubMed:19652181). Touch receptor neurons and GABAergic motor neurons have mis-localized presynaptic vesicles as indicated by aberrant expression of the protein snb-1 and distorted cell bodies (PubMed:19652181, PubMed:23527112). Reduced rate of inhibitory postsynaptic currents at the neuromuscular junctions of GABAergic motor neurons (PubMed:23527112). No effects on cholinergic synaptic transmission or snb-1 distribution in cholinergic motor neurons (PubMed:23527112). Increased rate of paralysis, in response to acetylcholine esterase inhibition by the drug Aldicarb, due to increased accumulation of acetylcholine in the extracellular fluid resulting permanent contraction of body wall muscles (PubMed:23527112). Knockout with a mec-7 heterozygous mutant, but not a null mec-7 mutant, rescues the touch sensitivity defect in the mec-15 single mutant (PubMed:19652181). {ECO:0000269|PubMed:19652181, ECO:0000269|PubMed:23527112, ECO:0000269|PubMed:8692859}. |
