Comments concerning this interaction

Proteins were detected in S2 cell nuclei using antibodies to the Myc tag for arm or the br core. The PLA signal develops only if probes to the two factors are in close proximity to each other (within tens of nanometers).

Source was cell extract of S2 cell line; proteins produced from transfected constructs.
