Angiogenin enhances tumorigenesis. However, the mechanisms of angiogenin-induced angiogenesis and cancer cell proliferation remain elusive. In this study, follistatin was identified as a binding partner of angiogenin by a yeast two-hybrid screen and confirmed by a pull-down experiment. The interaction of fluorescently tagged angiogenin and follistatin was monitored in real time by a laser confocal microscope and shown to localize at the sub-nuclear region of HeLa cells. Additional yeast two-hybrid analysis revealed that domains 2 and 3 of follistatin were the minimal structure requirement for angiogenin binding. These findings provide new clues for further studies on the mechanisms of angiogenin-induced angiogenesis or cancer cell growth. (C) 2007 Federation of European Biochemical Societies.
