1. A method of selecting isolated human cells comprising a transgene integrated into an endogenous glucocorticoid receptor (GR) gene, the method comprising:
a) introducing:
i) one or more polynucleotides encoding a first and second pair of zinc finger nuclease (ZFN); and
ii) a polynucleotide comprising a transgene flanked by homology arms that target a human glucocorticoid receptor (GR) gene into isolated human cells such that the transgene is integrated into an endogenous GR gene,
wherein
the first ZFN comprises:
a zinc finger DNA-binding domain comprising the following recognition helices in the following order:
| ||||||||||||||||||||||||||
and
the second ZFN comprises:
a zinc finger DNA-binding domain comprising the following recognition helices in the following order:
| ||||||||||||||||||||||||||
or
the first ZFN comprises:
a zinc finger DNA-binding domain comprising the following recognition helices in the following order:
| ||||||||||||||||||||||||||
and
the second ZFN comprises:
a zinc finger DNA-binding domain comprising the following recognition helices in the following order:
| ||||||||||||||||||||||||||
and
b) contacting the isolated human cells obtained in step a) with a corticosteroid such that cells not comprising the integrated transgene are killed and cells comprising the transgene integrated into the endogenous GR gene are selected.
