Human GPR14 polypeptides and polynucleotides and methods for producing such polypeptides by recombinant techniques are disclosed. Also disclosed are methods for utilizing Human GPR14 polypeptides and polynucleotides in the design of protocols for the treatment of ischemic coronary artery disease (angina and myocardial infarction); atherosclerosis; metabolic diseases (e.g. diabetes); CHF/myocardial dysfunction; arrhythmias; restenosis; hypertension; hypotension; pulmonary disease (hypertension, COPD, asthma); fibrotic vasculopathies (diabetes, SLE, AS, Reynaud's); cerebrovascular events (e.g. hemnorrhagic and ischemic stroke); neurogenic inflammation/migraine; hematopoietic disorders; ARDS; cancer; autoimmune diseases (e.g. HIV-1 and -2 infection and AIDS); gastrointestinal and genitourinary disturbances (e.g. ulcers); endocrine disorders; fibroproliferative disorders (e.g. psoriasis); inflammatory disease (e.g. RA, Crohn's, IBS); benign prostatic hypertrophy; renal failure and glomerulopathies; disease states, both cardiovascular and non-cardiovascular, which are characterized by excessive vasoconstriction, myocardial dysfunction and/or aberrant fibroproliferative/inflammatory responses; psychotic and neurological disorders, including anxiety, schizophrenia, manic depression, delirium, dementia, severe mental retardation, Parkinson's disease, and dyskinesias, infections such as bacterial, fungal, protozoan and viral infections; pain; eating disorders, such as obesity, anorexia, and bulimia; asthma; urinary retention; oteoporosis; allergies; Huntington's disease or Gilles de la Tourette's syndrome, among others and diagnostic assays for such conditions.
