Polypeptide and dna thereof useful as a neovascular marker

Abstract

A marker for neovascularization, vascular disease, inflammatory disease, entoptic neovascular disease, reproductive system disease, central nervous system disease and cancer, the method of detection of the marker and a diagnosis kit of the diseases are provided. Additionally, therapeutic agents of the diseases are provided. The expression of KIAA1036 is enhanced in ovarian cancer and large bowel cancer and KIAA1036 expresses in umbilical vein endothelial cell and inhibits DNA synthesis in the cells, cell migrating and lumen formation. Therefore KIAA1036 is useful as a marker for neovascularization, vascular disease, inflammatory disease, entoptic neovascular disease, reproductive system disease, central nervous system disease or cancer. Additionally, KIAA1036 is useful for screening of agonists, antagonists, DNA synthesis inhibitors, cell migrating inhibitors and neovascular inhibitors. The substances obtained by the screening, KIAA1036 and the antibodies are useful as therapeutic agents the above disease.
