We investigate Yangian invariance of deformed on-shell diagrams with D=4, N=4superconformal symmetry. We find that invariance implies a direct relationshipbetween the deformation parameters and the permutation associated to theon-shell graph. We analyse the connection with deformations of scatteringamplitudes in N=4 super-Yang-Mills theory and the possibility of using thedeformation parameters as a regulator preserving Yangian invariance. A study ofhigher-point tree and loop graphs suggests that manifest Yangian invariance ofthe amplitude requires trivial deformation parameters.
