Comments concerning this interaction

Source was embryonic nuclear extract of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.

(Poux et al., 2001)

The interaction of Pc and E(z) is seen only in early embryos, not in late embryos. This presumably reflects a transient interaction of E(z)-containing PRC2 and Pc-containing PRC1 complexes.
