Comments concerning this interaction

Source was embryos of wild-type fly line; protein produced from endogenous gene.

The lola zf5 (lola-PD) 105 kDa isoform was immunoprecipitated using the isoform-specific 7F1 monoclonal antibody. Other coimmunoprecipitated isoforms of lola (of different molecular weight) were detected using a polyclonal lola antiserum.

Comments concerning this interaction

From an analysis of many TF-ChIP data sets, TF-TF interactions were predicted on the basis of regular DNA sequence motif arrangements. 27 predicted TF-TF interactions were tested using a pull down assay that measures the \'Luminescence Intensity Ratio\'. A cut-off of 7 was used, well above values for six negative controls.

Homotypic interactions confirmed for lola-PA, lola-PD and lola-PQ isoforms.

Interaction in vitro; bait produced by coupled in vitro translation; prey produced by coupled in vitro translation.

Comments concerning this interaction

MW values were determined from column calibration with standard proteins in addition to staining. lola forms multimers. Mutations in hydrophobic residues to break H-bonds (proline), increase polarity (lysine) or traditional alanine, all decreased hexamer formation.

Interaction in vitro; protein produced as a recombinant fusion protein in bacterial system.
