Source was nuclear extract of S2 cell line; bait produced from endogenous gene; prey produced from endogenous gene.

Nuclear extract was fractionated on a glycerol gradient and fractions containing brm and osa were used for immunoprecipitation.

osa coimmunoprecipitates brm and Snr1 (Brahma complex), but not Iswi or ash2.

osa exists in a subset of brm-containing complexes.

Source was nuclear extract of S2 cell line; bait produced from endogenous gene; prey produced from endogenous gene.

Source was pupal extracts; bait produced from endogenous gene; prey produced from endogenous gene

<note> The E1 mutant form of Snr1 carrying a G256D substitution is capable of interacting with osa.
