    摘要: The invention describes the finding that 4-(4-dimethylaminostyrl)-N-methylpyridinium or ASP+ is a fluorescent substrate that is transported by several neurotransmitter transporters. Provided are methods for the analysis of neurotransmitter transport and binding using ASP+. The invention also provides rapid methods for screening for modulators of neurotransmitter transport. As neurotransmitter transporter defects are associated with numerous neurological disorders, the invention also provides methods for treating neurotransmitter transport-associated defects/conditions using the modulators identified by the screening methods of the invention.

    摘要: The serotonin transporter (SERT) is a target of various therapeutic agents used in the treatment of neurological and neurodegenerative disorders. The present invention provides novel forms of SERT that lacks high affinity recognition of specific serotonin reuptake inhibitors (SSRIs). The present invention therefore provides a novel target for use in screening and model development that can aid both the discovery of new medications and the discovery of novel pathways impacted in parallel with SERT blockade. Such novel targets can help identify new SSRI's with unique modifications and lead to discovery of pathways that secondarily support the therapeutic activity of these agents.

    摘要: The anatomical distribution, nucleic acid sequence, pharmacological properties, and inferred structural features of a cDNA encoding a high affinity, Na.sup.+ -dependent rat brain L-proline transporter is described. The expression of this carrier in subpopulations of putative glutamatergic pathways supports a specific role for L-proline in excitatory amino acid neurotransmission. The cloned transporter cDNA predicts a 637 amino acid protein with 12 putative transmembrane domains and exhibits 44%-45% amino acid sequence identity with other neurotransmitter transporters. These findings support a synaptic role for L-proline in specific excitatory pathways in the CNS. The sequence can be used for expression of the transporter molecule, to make probes for the same protein from other species and related proteins, in diagnostic assays, and to design functional and structural analogs for use in research and possible clinical treatments. The protein is useful in making antibodies, conducting research studies, and design of therapeutic transporter modulators for clinical treatments.
