PROBLEM TO BE SOLVED: To provide new polypeptides having diagnostic or therapeutic advantages, and to provide a method for identifying nucleic acid molecules encoding the same. SOLUTION: The isolated nucleic acid molecules comprise: a nucleotide sequence selected from among the group consisting of (a) a specific nucleotide sequence; (b) a nucleotide sequence of a DNA insert in ATCC accession numbers PTA-1753 and PTA-1755; (c) a nucleotide sequence encoding a specific polypeptide; (d) a nucleotide sequence hybridizing under moderately or highly stringent conditions to any complements of (a) to (c); and (e) a nucleotide sequence complementary to any of (a) to (c).
