Abstract
The present invention provides rhesus monkey dickkopf-1 (rhDkk-1) and nucleotide sequences encoding it. Also provided herein are recombinant vectors, and recombinant hosts comprising rhDkk-1-encoding nucleotide sequences. Isolated rhDkk-1 can be used to screen and identify novel osteoanabolic compounds that stimulate bone formation for the treatment of osteoporosis or other disorders characterized by insufficient bone mass.
Claims6
An isolated and purified rhesus dickkopf-1 (rhDkk-1) polypeptide comprising the sequence of amino acids as set forth in SEQ ID NO:2.
A method for determining whether an analyte is an antagonist of Dickkopf1 (Dkk-1) comprising:
- (a) providing a polypeptide comprising the extracellular domain of a Dkk-1 receptor;
- (b) contacting the polypeptide with a rhesus monkey Dkk-1 (rhDkk-1) polypeptide comprising the sequence of amino acids as set forth in SEQ ID NO:2 and the analyte;
- and
- (c) determining whether binding of the rhDkk-1 to the polypeptide is decreased in the presence of the analyte, wherein a decrease in the binding indicates that the analyte is an rhDkk-1 antagonist.
