  At the top of the S1 subsite cylinder are two “cap” residues: E572 and M1034 [13]. Atomic structures of PfA-M1 have revealed important clues into potential roles for the cap residues in substrate selection. In the PfA-M1:bestatin co-crystal structure ([13]; Fig. 1), the P1 phenyl ring occupies the S

  2023-08-24

  

  Since the cloning of ARs in the beginning of the 1990s, the efforts to characterize them have led to the accumulation of a substantial amount of experimental data. Decades of site-directed mutagenesis (SDM; Box 1) studies, in combination with pharmacological data and computational modeling, have pav

  2023-08-24

  

  Some alterations in the integrity of cell membranes caused by toxic agents can be determined by measuring certain enzymes released by damaged cells [8]. The cholinesterases, for example, catalyze the hydrolysis of ITMN-191 (ACh) in choline and acetic acid. Theses enzymes are divided into two types:

  Regarding androgens, it is known that they are also essential for reproductive success (Walters et al., 2010). At the molecular level, their effects are produced mainly by dihydrotestosterone (DHT), arising from the conversion of testosterone by the enzyme 3-oxo-5-alpha-steroid-4-dehydrogenase (enco

  V-ATPase is a complex enzyme that is composed of several subunits, which are assembled into two domains: trans-membrane (V0) and cytosolic (V1) domains [3,5]. Epididymal epithelial SANT-1 of rats has been reported to contain V-ATPase which is distributed at the apical pole of the narrow and clear ce

  To elucidate this relationship, we developed a spatial model of Ca-influx through N-methyl-D-aspartate receptor (NMDAR), CaMKII/PP1 activation, and AMPAR insertion in a realistic spine geometry. Using this model, we show that i) variables in membrane voltage mediated Ca-influx, particularly the numb

  Discussion AhR is a receptor that binds to a great variety of lipophilic compounds, in particular those containing at least one aromatic ring (Abel and Haarmann-Stemmann, 2010, Guyot et al., 2013, Hahn, 2002). The main known function of this receptor is to induce the metabolism of these compounds

  When added to the culture medium, extracellular ATP is metabolized into adenosine by ectonucleotidases, and ARs are then activated by adenosine with concentrations in the micromolar range [27]. However, our study showed that activation of ARs by exogenous adenosine could not induce the odontoblasti

  In this study, we obtained the absorbance and photoluminescence (PL) of monoamine transporter polymerized with various types of actin-binding proteins in order to probe the actin structures in situ without labeling. Both optical measurements have been useful in examining biomaterials such as DNA an

  Although effects of low concentrations of agonist were not as thoroughly documented for heteromeric receptors such as the major farnesoid x receptor α4β2 nAChR, a similar mechanism of action was described to explain the potentiation of these receptors with low concentrations of acetylcholine-estera
