Comments concerning this interaction

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

(Huang et al., 2013)

3 of 47 clones recovered using Smurf as bait represented ptc clones.

(Huang et al., 2013)

All three "C2-WW-HECT" E3 family proteins can bind to the C-terminal domain of ptc : Su(dx), Nedd4 and Smurf.

(Huang et al., 2013)

Two-hybrid system: yeast GAL4-BD/GAL4-AD
