Transcription factor required for zygotic genome activation (ZGA), a critical event in early embryonic development during which the developmental control passes from maternally provided mRNAs to the expression of the zygotic genome after fertilization . Protein produced from maternal transcripts that binds and activates expression of key ZGA marker genes, such as NANOGNB, ZSCAN4, DUXB, KLF5 and DPPA3 . Binds to regulatory DNA sequences containing a 5'-TAATCC-3' sequence motif (By similarity).
