General Purpose Coarse-Grained Force Field 
Cool stuff! Dry Martini coupled to stochastic rotational dynamics to account for solvent hydrodynamics:

A topical review on CG simulations of GPCRs, featuring many Martini-based works, is now online at ACS Chemical Reviews:

Another paper from the Sansom lab showing how protein-protein and protein-lipid PMFs with MARTINI can be efficiently obtained using replica-exchange umbrella sampling:
We proudly present the most recent work of F. J. van Eerden a PhD student in our lab, soon to graduate.

Check out this paper, a nice example of how metadynamics can be combined with Martini for efficient sampling of protein-protein binding free energies:
