Comments concerning this interaction

Source was cell extract of HEK293 cell line; bait produced from transfected construct; prey produced from transfected construct.

Mad and pan form a complex that competes with arm-pan binding. Mad and arm do not bind in this experiment.

Bait expressed in transfected HEK293T cells.

Prey expressed in transfected HEK293T cells.

Activation of BMP signaling abolishes the interaction of Mad with pan, presumably due to phosphorylation of the Mad C-terminus.
