Abstract

Problem to be Solved An object of the present invention is to provide a separase sensor for visualizing separase activity in a living cell. Another object is to develop a function analysis system of cell division using the separase sensor and further obtain a simple screening method for an anticancer agent. Solution The separase sensor of the present invention has two types of fluorescent proteins different in fluorescence wavelength at both ends of an amino acid sequence containing a separase cleavage site and a localization-targeting sequence targeting to a specific site within a cell. Since timing of activating separase and location of separase in a cell can be specified by use of the sensor, cell division can be analyzed and an anticancer agent can be screened.
