Comments concerning this interaction

Source was yeast cell line; bait produced as transgenic fusion protein; prey produced as transgenic fusion protein (prey from embryo cDNA expression library).

The corto chromodomain is not sufficient for interaction with CycG.

Two-hybrid system: yeast LexA-BD/B42-AD
