TLDR
The structure of the G protein heterotrimer Gi alpha 1(GDP)beta 1 gamma 2 (at 2.3 A) reveals two nonoverlapping regions of contact between alpha and beta, an extended interface between beta and nearly all of gamma, and limited interaction of alpha with gamma as mentioned in this paper.About:

Integrins: Bidirectional, Allosteric Signaling Machines
TL;DR: Current structural and cell biological data suggest models for how integrins transmit signals between their extracellular ligand binding adhesion sites and their cytoplasmic domains, which link to the cytoskeleton and to signal transduction pathways.

Cytochrome c and dATP-Dependent Formation of Apaf-1/Caspase-9 Complex Initiates an Apoptotic Protease Cascade
Peng Li,Deepak Nijhawan,Imawati Budihardjo,Srinivasa M. Srinivasula,Manzoor Ahmad,Emad S. Alnemri,Xiaodong Wang +6 more
TL;DR: Mutation of the active site of caspase-9 attenuated the activation of cazase-3 and cellular apoptotic response in vivo, indicating that casp enzyme-9 is the most upstream member of the apoptotic protease cascade that is triggered by cytochrome c and dATP.

TL;DR: This crystal structure represents the first high-resolution view of transmembrane signalling by a GPCR and the most surprising observation is a major displacement of the α-helical domain of Gαs relative to the Ras-like GTPase domain.

TL;DR: The accessibility of atoms in the twenty common amino acids in model tripeptides of the type Ala-X-Ala are given for defined conformation and the larger non-polar amino acids tend to be more “buried” in the native form of all three proteins.
