  4. NTR2 Isoform


NTR2 (neurotensin receptor 2) belongs to the G protein-coupled receptor family that activates a phosphatidylinositol-calcium second messenger system. Binding and pharmacological studies demonstrate that this receptor binds neurotensin as well as several other ligands already described for neurotensin NT1 receptor. However, unlike NT1 receptor, this gene recognizes, with high affinity, levocabastine, a histamine H1 receptor antagonist previously shown to compete with neurotensin for low-affinity binding sites in the brain. These activities suggest that this receptor may be of physiological importance and that a natural agonist for the receptor may exist.

    Levocabastine (R 50547) hydrochloride is a potent and selective histamine H1-receptor antagonist. Levocabastine hydrochloride is also a selective, high affinity neurotensin receptor subtype 2 (NTR2) antagonist, with a Ki of 17 nM for mNTR2. Levocabastine hydrochloride can act as a VLA-4 antagonist, interferes with conjunctival eosinophil infiltration in allergic conjunctivitis (AC).
