Male stickleback fish develop red colour on their ventral side in the breeding season and maintain territories. 

When a conspecific male intruder enters their territory, resident males perform an aggressive display. 

The ethologist Niko Tinbergen presented models of different shapes to territorial male stickleback fish. He found that models of any shape elicited aggressive displays, provided the ventral part of the models was coloured red.

ATP is required for the binding, but is not hydrolyzed until a later stage. The transcription factor ABF1 binds to the B3 element; this assists initiation by affecting chromatin structure, but it is the events that occur at the A and B1 elements that actually cause initiation
