Herein, the restricted expression of serum response factors (SRF) closely overlapped
withNkx2-5 and GATA4 transcripts in early chick embryos coinciding with the earliest
appearance of cardiac α-actin (αCA) transcripts and nascent myocardial cells. The
combinatorial expression of SRF, a MADS box factor Nkx2-5 (a NK4 homeodomain), and/or
GATA4, a dual C4 zinc finger protein, in heterologous CV1 fibroblasts and Schneider 2
insect cells demonstrated synergistic induction of αCA promoter activity. These three factors …
