摘要 |
The present invention is directed to a method for localising, in chromatin or DNA, the binding loci of a chromatin or DNA binding protein comprising the following steps: a) tethering, directly or indirectly, an enzyme with regulatable activity to said chromatin binding protein, b) transiently activating the regulatable enzymatic activity bound to the targeted chromatin and c) mapping the enzymatically-modified genomic sites introduced by the enzyme into the chromatin. According to an embodiment of the invention, the regulatable enzyme is a regulatable protease. The mapping step may be carried out on specific DNA fragments, or on a chromosome-wide scale or a genome-wide scale. The present invention is also directed to kits for carrying out the methods of the invention.
