ApTrkl, an Aplysia Trk-like receptor, is required for serotonin (5-HT)-induced activation of ERK and LTF, which underlies behavioral sensitization. We observed constitutive activation of ApTrkl by overexpression, which is dependent on kinase activity. Two modes of internalization were revealed; kinase activity-dependent constitutive internalization and kinase activity-independent internalization induced by 5-HT. Both modes of internalization were independent of a ligand, and the action of 5-HT was mediated through G protein-coupled receptors (GPCRs). Surprisingly, methiothepin, an antagonist to 5-HT GPCRs, increased activation of endogenous ApTrkl to the same level as 5-HT, suggesting a transactivation mechanism due to a novel coupling of G...
