Novel polypeptide, cDNA encoding the same, and use thereof

摘要

Novel polypeptides produced by a human adult brain tissue, a cell line derived therefrom, a cell line derived from human bone marrow and a human umbilical cord venous endothelial cell line; a process for producing these polypeptides; cDNAs encoding the polypeptides; fragments hybridizable selectively with the cDNA sequences; replication or expression plasmids having the cDNAs integrated thereinto; host cells transformed by the plasmids; antibodies against the above polypeptides; and medicinal compositions containing the peptides or the antibodies.
