Protein kinase CK2 is a ubiquitous eukaryotic ser/thr protein kinase. The active holoenzyme is a heterotetrameric protein corn posed of catalytic (α and α') and regulatory (β) subunits that phosphorylates many different ...

The major fibronectin (FN)-binding α5β1 and αvβ3 integrins exhibit cooperativity during cell adhesion, migration and mechanosensing, through mechanisms that are not yet fully resolved. Exploiting mechanically tunable ...

Secondary structure elements are generally found in almost all protein structures revealed so far. In general, there are more β-sheets than α helices found inside the protein structures. For example, considering the PDB, ...

Alterations in the levels of copper in brain tissue and formation of α-synuclein (αS)-copper complexes might play a key role in the amyloid aggregation of αS and the onset of Parkinson's disease (PD). Recently, we demonstrated ...

Two saponins were isolated from the leaves of Lippia alba. Their structures were established using one- and two-dimensional NMR spectroscopy and mass spectrometry. These new compounds were elucidated as 3-Ο-β-D- ...

In this work, the interaction of (±)-bupropion [(±)-BP] and (±)-2-(N-tert-butylamino)-3’-iodo-4’- azidopropiophenone [(±)-SADU-3-72] with the human (h) α3β4 nicotinic acetylcholine receptor (AChR) is determined by functional ...

The interaction of the selective norepinephrine reuptake inhibitor (-)-reboxetine with the human α4β2 nicotinic acetylcholine receptor (nAChR) in different conformational states was studied by several functional and ...

Trypanosoma cruzi, the protozoa that causes Chagas disease in humans, is transmitted by insects from the Reduviidae family. The parasite has developed the ability to change the structure of the surface molecules, depending ...
