Targeted Disruption of Mouse Yin Yang 1 Transcription Factor Results in Peri-Implantation Lethality
1 Oct 1999
Abstract excerpt
Yin Yang 1 (YY1) is a zinc finger-containing transcription factor and a target of viral oncoproteins. To determine the biological role of YY1 in mammalian development, we generated mice deficient for YY1 by gene targeting. Homozygosity for the mutated YY1 allele results in embryonic lethality in the mouse. YY1 mutants undergo implantation and induce uterine decidualization but rapidly degenerate around the time...
