flp-3 encodes nine copies of a GTMRFamide-containing peptide that is predicted to function as a neuropeptide that inhibits pharyngeal action potential in a manner similar to octopamine without having a significant effect on basal resting membrane potential; flp-3 is expressed in three pairs of neurons IL1D, OLL, URB.
Involved in negative regulation of action potential; neuropeptide signaling pathway; and regulation of pharyngeal pumping. Predicted to be located in extracellular region. Expressed in head; motor neurons; sensory neurons; somatic nervous system; and in male.
