Comments concerning this interaction

Nuclear extract was purified through several different chromatographic steps, selecting for nucleosome disruption activity.

(Tsukiyama et al., 1995)

E(bx), Iswi, Caf1 and Nurf-38 cosediment as part of the approximately 500 kDa NURF complex.

(Tsukiyama et al., 1995)

Source was embryonic nuclear extract of wild-type fly line; proteins produced from endogenous genes.
