in sensory neurons of aplysia , the s-k- channel is under the dual modulatory control of 5-hydroxytryptamine ( 5-ht ) , which decreases the number of active s channels through cyclic amp-dependent phosphorylation , and the neuropeptide fmrfamide , which increases the probability of s-channel opening through the 12-lipoxygenase metabolite 12-hydroperoxyeicosatetraenoic acid ( 12-hpete ) .
