Abstract: The present invention relates to a method of forming a peptide-receptor complex with zsig33 polypeptides and their receptors as well as antibodies. Methods of modulating gastric contractility, nutrient uptake, growth hormones, the secretion of digestive enzymes and hormones, and/or secretion of enzymes and/or hormones in the pancreas are also included.

Abstract: The current invention discloses nucleic acid and amino acid sequences for novel organic anion transfer proteins (“OATPs”). The invention encompasses the OATPs described herein, together with vectors containing the cDNA sequences, host cells containing the vectors and polypeptides having all or part of an OATP. Also encompasses are uses for OATPs for targeting drugs to specific organs and for modulating the concentration of endogenous substrates.

Abstract: The present invention relates to a chimeric chemokine receptor comprising two components: a first sequence comprising the N terminus through the last residue of the seven helix TM region of a first chemokine receptor joined with a second sequence comprising the C terminus of a second chemokine receptor extending from the first intracellular residue of the chemokine receptor to the last residue of the chemokine receptor. The chimeric chemokine receptor can be employed in various applications, such as ligand binding and screening assays and signalling assays. The chimeric chemokine receptor can also form a component of a chemokine receptor modulator design program.
