Current force fields tend to overstabilize protein-protein interactions, and Martini is no exception. A recent paper by the Vattulainen group shows the stickiness is also haunting membrane embedded proteins:

We are working hard to improve the protein-protein interactions in the forthcoming Martini 3.0 force field, featuring a thoroughly recalibrated interaction matrix, with a planned release early 2018.
