Structural Insights into the Process of GPCR-G Protein Complex Formation.

abstract：:Recent results from diverse organisms point to a self-reinforcing network of interactions among the three best-characterized covalent modifications that mark heterochromatin: histone hypoacetylation, histone H3-Lys9 methylation, and cytosine methylation. These modification systems suggest a mechanistic basis for sprea...
