Buccalin is present in the cholinergic motor neuron B16 of Aplysia and it depresses accessory radula closer muscle contractions evoked by stimulation of B16.
The accessory radula closer (ARC) buccal muscle motor neuron B16 is buccalin-immunoreactive and it synthesizes a peptide with chromatographic properties identical to those of buccalin. Terminal varicosities in the ARC muscle are buccalin-immunoreactive, and buccalin reduces muscle contractions evoked by stimulation of neuron B16, probably by a presynaptic action.
