abstractText | The multifunctional transcription factor TFII-I encoded by the Gtf2i gene is expressed at the two-cell stage, inner cell mass, trophectoderm, and early gastrula stages of the mouse embryo. In embryonic stem cells, TFII-I colocalizes with bivalent domains and depletion of Gtf2i causes embryonic lethality, neural tube closure, and craniofacial defects. To gain insight into the function of TFII-I during late embryonic and postnatal stages, we have generated a conditional Gtf2i null allele by flanking exon 3 with loxP sites. Crossing the floxed line with the Hprt-Cre transgenic mice resulted in inactivation of Gtf2i in one-cell embryo. The Cre-mediated deletion of exon 3 recapitulates a genetic null phenotype, indicating that the conditional Gtf2i line is a valuable tool for studying TFII-I function during embryonic development. genesis 54:407-412, 2016.
