Fig. 1: Timing of zygotic transcriptional onset and NF-Y activity in different vertebrates.
From: The role(s) of NF-Y in development and differentiation

The main transcription factors (TFs) participating in zygotic genome activation are indicated on the right. The transcript levels of NF-Y subunits in cow have been reported by Halstead et al. [54]. NPS = NANOG, POU5F3, SOX19B.
