<P>PROBLEM TO BE SOLVED: To directly clone a new DNA containing a region encoding a protein from a cDNA library derived from the human adult whole brain, the human tonsils, the human adult hippocampus and the human fetal whole brain, determine the base sequence thereof and further identify functions thereof. <P>SOLUTION: This DNA comprises a base sequence encoding a polypeptide of the following (a) or (b). (a) a polypeptide composed of a plurality of the same or substantially the same amino acid sequences as a plurality of specified amino acid sequences estimated as a plurality of new proteins derived from humans or (b) a polypeptide composed of an amino acid sequence in which a part of amino acids are deleted, substituted or added in the amino acid sequence represented by any one of the polypeptide and having a biological activity substantially homogeneous with functions of the polypeptide (a). A recombinant polypeptide is encoded with the DNA. A protein comprises the polypeptide. <P>COPYRIGHT: (C)2003,JPO |
