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

The SNAP/PBP complex was isolated from soluble nuclear extract by fractionation on DEAE-cellulose and heparin columns.

DNA-binding subunits within the SNAP/PBP complex were detected by photo-cross-linking and molecular weight estimation of proteins on a gel. The identity of these proteins was later determined by using antibodies and supershift assays in a subsequent study (FBrf0174956).

Pbp45, Pbp49 and Pbp95 are part of the SNAP (small nuclear RNA activating protein) complex, also known as the PBP (PSE binding protein) complex, involved in snRNA transcription.

Interaction in vitro; bait produced as recombinant fusion protein in transfected S2 cell extract; prey produced from endogenous gene.

Pbp45-containing complexes were affinity purified from transfected S2 cell extracts and used in electromobility shift assays using [32]P labeled DNA containing the U1 snRNA \'PSEA\' motif. The presence of other proteins in the Pbp45-DNA complex was assessed using antibodies to supershift the apparent migration of the protein:DNA complex.
