Human HBMBU14 polypeptides and DNA (RNA) encoding such HBMBU14 and a procedure for producing such polypeptides by recombinant techniques is disclosed. Also disclosed are methods for utilizing such HBMBU14 for the treatment of infections such as bacterial, fungal, protozoan and viral infections, particularly infections caused by HIV-1 and HIV-2, pain, cancers, anorexia, bulimia, asthma, Parkinson's disease, acute heart failure, atherosclerosis, hypotension, hypertension, urinary retention, osteoporosis, angina pectoris, myocardial infarction, ulcers, asthma, allergies, benign prostatic hypertrophy and psychotic and neurological disorders, including anxiety, schizophrenia, manic depression, delirium, dementia or severe mental retardation, and dyskinesias, such as Huntington's disease or Gilles dela Tourette's syndrome, among others, are also disclosed. Also disclosed are diagnostic assays for detecting diseases related to mutations in the nucleic acid sequences and altered concentrations of the polypeptides. Also disclosed are diagnostic assays for detecting mutations in the polynucleotides encoding the HBMBU14 and for detecting altered levels of the polypeptide in a host.
