This mouse line was made by gene targeting and designed to express an HA-tagged version of the transcription factor Neurog3 (Ngn3). The Lox71 and Lox2272 sites were inserted flanking the Ngn3 coding sequence. Within the flanked region an HA-tag was placed at the N-terminus of the Ngn3 protein. This allele can be used to study chromatin and protein-protein interactions of Ngn3. Additionally, the Lox71 and Lox2272 sites allow for manipulations of the flanked region by Recombinase-Mediated Cassete Exchange (RMCE) in ES cells.

Additional Information

Cryopreserved in homozygous state Neurog3{(HA/HA)}.

The targeting vector contains a 5.5 kb 5’ arm and a 3.5 kb 3’arm.  Lox71 and Lox2272 sites were inserted flanking the Ngn3 gene, where Ngn3 cDNA was replaced with that encoding for an HA-tagged Ngn3 protein.  The vector also contains a FRT-flanked Pgk-Puro-deltaTK cassette for positive selection by puromycin (targeting events) and negative selection by ganciclovir (RMCE events).
