The invention also provides expression vectors, host cells, agonists, antibodies and antagonists. The invention also provides methods for treating and preventing disorders associated with expression of CORN. Determination of body plan is encrypted within embryonic cell lineages, and the fate of specific embryonic cell lineages is determined before fertilization, during oogenesis. Oogenesis and embryogenesis are regulated by interactions between environmental, extracellular, and intracellular signals.
More particularly, it relates to the area of human dopamine-like G protein-coupled receptor and its regulation. The family of G-protein coupled receptors GPCR includes receptors for hormones, neurotransmitters, growth factors, and viruses.
Specific examples of GPCRs mclude receptors for such diverse agents as calcitonin, adrenergic hormones, endothelin, cAMP, adenosine, acetylcholine, serotonin, dopamine, histamine, thrombin, kinin, follicle stimulating hormone, opsins, endothelial differentiation gene-1, rhodopsins, odorants, cytomegalovirus, G-proteins themselves, effector proteins such as phospholipase C, adenyl cyclase, and phosphodiesterase, and actuator proteins such as protein kinase A and protein kinase C.
The GPCR protein superfamily now contains over typ. The superfamily can be broken down into five families: GPCRs possess seven conserved membrane-spanning domains connecting at least eight divergent hydrophilic loops.
GPCRs also known as 7TM receptors have been characterized as including these seven conserved hydrophobic stretches of about 20 to 30 amino acids, connecting at least eight divergent hydrophilic loops. Most GPCRs have single conserved cysteine residues in each of the first two extracellular loops, which form disulfide bonds that are believed to stabilize functional protein structure.
TM3 has been implicated in signal transduction. Phosphorylation and lipidation palmitylation or farnesylation of cysteine residues can influence signal transduction of some GPCRs.
The hydrophilic sockets are surrounded by hydrophobic residues of the GPCRs. The hydrophilic side of each GPCR transmembrane helix is postulated to face inward and form a polar ligand binding site.
GPCRs are coupled inside the cell by heterotrimeric G-proteins to various intracellular enzymes, ion channels, and transporters see Johnson et al, Endoc.
Different G-protein alpha-subunits preferentially stimulate particular effectors to modulate various biological functions in a cell.
For example, in one form of signal transduction, the effect of hormone binding is the activation inside the cell of the enzyme, adenylate cyclase. Enzyme activation by hormones is dependent on the presence of the nucleotide GTP. GTP also influences hormone binding.
A G-protein connects the hormone receptor to adenylate cyclase. The GTP-carrying form then binds to activated adenylate cyclase. Thus, the G-protein serves a dual role, as an intermediate that relays the signal from receptor to effector, and as a clock that controls the duration of the signal.
Over the past 15 years, nearly therapeutic agents targeting GPCRs receptors have been successfully introduced onto the market.
This indicates that these receptors have an established, proven history as therapeutic targets.

Dopamine andDopamine Receptors Dopamine is a neurotransmitter that participates in a variety of different functions mediated by the nervous system, including vision, movement, and behavior see U. A great deal of information has accumulated on the biochemistry of the Dl and D2 dopamine receptors, and methods have been developed to solubilize and purify these receptor proteins see Senogles et al,Biochemistry 25, ; Sengoles et al,J.
The Dl dopamine receptor in several tissues appears to be a glycosylated membrane protein of about 72 kD Amlaiky et al,Mol. Much less is known about a recently discovered additional dopamine receptor, termed D3 Sokoloffet flJ,Nature The three different dopamine receptors Dl, D2, D3 have been cloned as a result of nucleotide sequence homology which exists between these receptor genes Bunzow et al,Nature; Grandy et al,Proc.
The antipsychotic clozapine is useful for socially withdrawn and treatment-resistant schizophrenics see Kane et al,Nature, but unlike other antipsychotic drugs, clozapine does not cause tardive dyskinesia see Casey,Psychopharmacology 99, Clozapine, however, has dissociation constants for D2 and D3 which are 3 to fold higher than the therapeutic free concentration of clozapine in plasma water Ackenheil et al,Arzneim-Forsch 26, ; Sandoz Canada, Inc.
Summary of preclinical and clinical data. This suggests the existence of dopamine receptors more sensitive to the antipsychotic clozapine than those known in the prior art heretofore. This and other objects of the invention are provided by one or more of the embodiments described below.
