Abstract

The present invention provides amino acid sequences of peptides that are encoded by genes within the human genome, the secreted peptides of the present invention. The present invention specifically provides isolated peptide and nucleic acid molecules, methods of identifying orthologs and paralogs of the secreted peptides, and methods of identifying modulators of the secreted peptides.
