The present invention relates generally to novel tors or secreted polypeptides, include polypeptides and nucleic acids embodied in cDNA clones and the polypep active fragments of polypeptides that are produced by cells tides they encode. Sequences encompassed by the invention and exported extracellularly. Secreted proteins also include include, but are not limited to, the polypeptide and poly extracellular fragments of transmembrane proteins that are nucleotide sequences of the molecules shown in the proteolytically cleaved, and extracellular fragments of cell Sequence Listing and corresponding molecular sequences Surface receptors; these fragments may be soluble. Many found at all developmental stages of an organism, genes or and widely variant biological functions are mediated by a gene segments designated by the Sequence Listing, and their wide variety of different types of secreted proteins.
