Source was embryos of wild-type fly line; bait produced from endogenous gene; prey produced from endogenous gene.
Pc, ph-p and Psc coimmunoprecipitate with TAF proteins, but not E(z) (a member of a distinct PcG complex).
The interaction of Taf5 with Pc is not dependent on DNA, as ethidium bromide does not disrupt their association.
Partially purified Bio-Rex70 fractions were used for this immunoprecipitation study.
