The present invention relates to a novel human peroxisome proliferator
activated receptor, hPPAR.gamma.. hPPAR.gamma. differs from the mouse
peroxisome proliferator activated receptor .gamma. in the nucleotide
sequence and the amino acid sequence. The invention provides isolated,
purified, enriched or recombinant nucleic acid encoding hPPAR.gamma.
polypeptides and vectors containing thereof, cells transformed with such
vectors, and methods of screening for agonists and antagonists of
hPPAR.gamma. polypeptides. The invention also provides isolated,
purified, enriched, or recombinant hPPAR.gamma. polypeptides, antibodies
having specific binding affinity to hPPAR.gamma. polypeptides, and
hybridomas producing such antibodies.
