Essential role of the TFIID subunit TAF4 in murine embryogenesis and embryonic stem cell differentiation

Abstract

The role of TFIID core module TAFs (TATA-binding protein-associated factors) in embryogenesis is unknown. Here, the authors show that Taf4 is essential at mid-gestation and for complete neuronal differentiation of embryonic stem cells, but that Taf4a and Taf4b are redundant at early embryonic stages.
