  • Patent number: 9273115
    Abstract: The present invention relates to a method for tightly temporally controlling the biological activity of a protein of interest in a vertebrate, upon induction of the activity of a fusion protein comprising said protein of interest and an ERM polypeptide containing a mutated ligand binding domain of the human oestrogen receptor ?, with a synthetic ligand that does not interfere with oestrogen signalling. In particular, the present invention concerns a method for generating tightly temporally-controlled targeted somatic mutations in a vertebrate, preferably a mouse, by inducing the activity of a fusion protein comprising a site-specific recombinase protein and an ERM polypeptide, with a synthetic ligand devoid of oestrogenic and anti-oestrogenic activities.
