Bone polypeptide-1
View Patent ↗The present invention relates to a bone polypeptide, particularly bone polypeptide-1 and nucleic acid molecules encoding the same. The present invention provides the human primary sequence of bone polypeptide-1 as well as sequences of vertebrate homologs. The invention also provides cell lines engineered to express the cDNA, antibodies to detect its translation products, and recombinant adenoviruses to deliver an expressible cDNA into a host. Bone polypeptide-1 can be utilized to treat diseases affecting renal and bone functions.
