Abstract excerpt
In mouse embryos, the Zfhx1 transcription factor genes, Sip1 and deltaEF1, are expressed in complementary domains in many tissues. Their possible synergism in embryogenesis was investigated by comparing the phenotype of Sip1-/-;deltaEF1-/- double homozygotes with single homozygous embryos. Unexpectedly, in Sip1-/- embryos deltaEF1 was ectopically activated, suggesting a negative regulation of deltaEF1 expression...
