1. Caricatura e reconhecimento de faces / Caricature and face recognition
A caricature is an exaggeration of distinctive facial features and is generally recognized just as well as an undistorted photograph of a face. Caricatures can be generated by exaggerating the differences between a face and a prototypical face (average face) and an anticaricature can be generated by reducing those differences. The aim of this study was to in

2. Crystal structure of the dimeric extracellular domain of human carbonic anhydrase XII, a bitopic membrane protein overexpressed in certain cancer tumor cells
Overexpression of the zinc enzyme carbonic anhydrase (CA; EC 4.2.1.1) XII is observed in certain human cancers. This bitopic membrane protein contains an N-terminal extracellular catalytic domain, a membrane-spanning α-helix, and a small intracellular C-terminal domain. We have determined the three-dimensional structure of the extracellular catalytic d

3. Lipid Protein Interactions Couple Protonation to Conformation in a Conserved Cytosolic Domain of G Protein-coupled Receptors*
The visual photoreceptor rhodopsin is a prototypical class I (rhodopsin-like) G protein-coupled receptor. Photoisomerization of the covalently bound ligand 11-cis-retinal leads to restructuring of the cytosolic face of rhodopsin. The ensuing protonation of Glu-134 in the class-conserved D(E)RY motif at the C-terminal end of transmembrane helix-3 promotes the
