AF-2

AF-2, KHEYLRF-amide, was isolated from a head extract of the nematode, Ascaris suum. The peptide produced multiple effects on muscle tension, markedly increasing the tension change associated with changes in muscle membrane potential. It had mainly inhibitory effects on Helix central neurones due to an increase in potassium conductance. KHEYLRF-amide has also been detected in Caenorhabditis elegans.
