Endocannabinoids (eCBs) are involved in the stress response and alterations in eCB signaling may contribute to the etiology of mood disorders. Exposure to chronic mild stress (CMS), a model of depression, produces downregulation of the cannabinoid 1 (CB1) receptor in the hippocampus of male rats. However, it is unknown how this stress-induced change in CB1(More)
Why does a given protein structure form and why is this structure stable? These fundamental biochemical questions remain fascinating and challenging problems because the physical bases of the forces that govern protein structure, stability and folding are still not well understood. Now, a general concept of hydrogen bonding in proteins is emerging. This(More)
Hfq is a thermostable RNA-binding bacterial protein that forms a uniquely shaped homohexamer. Based on sequence and structural similarity, Hfq belongs to the like-Sm (LSm) protein family. In spite of a rather high degree of homology between archaeal and eukaryotic LSm proteins, their quaternary structure is different, usually consisting of five to eight(More)
