2020-03-13

Generally, glycines (and other small residues such as alanine) present in a helical GxxxG-motif that are facing the same side of the helix form a uniform surface that enables direct contact with a second helix. Crystal structures of multipass membrane proteins have demonstrated that GxxxG-motifs are

One of the hallmarks of the terminal stages of apoptosis is the fragmentation of chromosomal DNA that proceeds in a two-step manner: the DNA is initially cleaved into 50–300kb fragments and eventually into oligonucleosomal pieces [12], [13]. The two major apoptotic nucleases are DNA fragmentation fa

Atg4 cleaves Atg8 at the peptide bond on the glycine residue at the C-terminus, thus allowing the conjugation of Atg8 to phosphatidylethanolamine (PE) with the participation of other autophagy molecules. Atg4 can also serve as a deconjugating enzyme, which cleaves the amide bond of the conjugated At

After repeated, intermittent exposure to a psychostimulant an augmentation of drug response to motor activity is commonly observed, a phenomenon known as behavioral sensitization (Kalivas and Stewart, 1991, Steketee and Kalivas, 2011). On the other hand, several reports have pointed out that stress

Animal studies investigating the role of D1 dopamine receptors in the PFC have focused on delayed response tasks, which require online maintenance of a previously presented stimulus. Striatal dopamine is thought to be important for flexibility and updating goal representations when new information i

The most common pathology associated with FGR is poor placental perfusion as a result of abnormal placentation [4]. Placental developmental disorders and insufficient hormone synthesis may lead to FGR [5,6]. However, the exact mechanism responsible for abnormal placental development remains unclear.

Methods Results First, we compared Aβ plaque number, Aβ concentration, and neurobehavior functions between naive APP/PS1 and APP/PS1xEP1−/− mice. Significantly lower Aβ burden in APP/PS1xEP1−/− mice was evidenced by fewer plaques in the hippocampal area and a lower concentration of soluble Aβ42

Cytochrome P450 monooxygenases Cytochrome P450 monooxygenases (P450s) belong to one of Nature’s most versatile group of enzymes for C–H functionalization and are able to perform challenging regioselective and stereoselective activations of remote, unactivated C(sp3)–H bonds, for which there are o

Preliminary studies suggest that dimerization of the AT1 receptor occurred during the biosynthesis in the endoplasmic reticulum before surface expression [27,40], which may explain the presenece of these citric acid before the addition of any ligand. Our results showed that the presence of Ang II

Materials and methods Results Discussion In addition, the responses of CYP450s induced by metalaxyl are species-specific in the four cells. For example, metalaxyl lead to induction of CYP1A1, CYP1A2, and CYP2B1 in HepG2 cells, CYP1A2 and CYP2B1 in H4IIE cells, CYP1A1 and CYP2B1 in LMH cells

The presence of H+-PPases in parasitic protists raises the question of the physiological role of these proteins. So far, they had been extensively characterized mainly in higher plants, and some prokaryotes [1], [2], [3], [4], [5], [6], [7], [16], [20]. A common feature to all these organisms is tha

Our structures also provide new insights into CRTH2 drug development. The ligand binding pocket revealed by our structures comprises many aromatic residues and a few polar residues at the distal end. Correspondingly, most CRTH2 antagonists share a similar structural feature characterized by an aceta
