Abstract: Putative Adrenomedullin Receptor polypeptides and polynucleotides and methods for producing such polypeptides by recombinant techniques are disclosed. Also disclosed are methods for utilizing Putative Adrenomedullin Receptor polypeptides and polynucleotides in the design of protocols for the treatment of infections such as bacterial, fungal protozoan and viral infections, particularly infections caused by HIV-1 or HIV-2; pain; cancers; diabetes, obesity; anorexia; bulimia; asthma; Parkinson's disease; acute heart failure; hypotension; hypertension, urinary retention, osteoporosis; angina pectoris; myocardial infarction, ulcers; asthma; allergies; benign prostatic hypertrophy; psychotic and neurological disorders, including anxiety, schizophrenia, manic depression, delirium, dementia, severe mental retardation and dyskinesias, such as Huntington's disease or Gilles dela Tourett's syndrome; and pre-eclampsia, among others and diagnostic assays for such conditions.
