Proteins (1 of 2) (image) Rice University Caption A combination of experimental and theoretical studies, in particular direct coupling analysis (DCA), revealed detailed interactions between NAF-1 (left) and Bcl-2 (right), two proteins involved in cellular life-and-death decisions. The green lines represent links between the proteins predicted by DCA.
