Vitamin A Transport Mechanism of the Multitransmembrane Cell-Surface Receptor STRA6. [PDF]

open access: yes, 2015
Vitamin A has biological functions as diverse as sensing light for vision, regulating stem cell differentiation, maintaining epithelial integrity, promoting immune competency, regulating learning and memory, and acting as a key developmental morphogen ...

Trio and CRMP2 regulate axon branching and Semaphorin3A signaling

open access: yesCommunications Biology
Trio is a neuronally expressed, Rac1- and RhoA-activating RhoGEF, that is required for neurodevelopment. Mutations affecting the Rac1-activating GEF domain of Trio are associated with profound neurodevelopmental delay and Trio knock-out is embryonic ...

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]

open access: yes, 2013
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Immunoprecipitation and Sequencing of Acetylated RNA

open access: yesBio-Protocol, 2019
Generation of the epitranscriptome through chemical modifications of protein-coding messenger RNAs (mRNAs) has emerged as a new mechanism of post-transcriptional gene regulation.

Marine furanocembranoids-inspired macrocycles enabled by Pd-catalyzed unactivated C(sp3)-H olefination mediated by donor/donor carbenes

open access: yesNature Communications, 2021
Furanocembranoid-like natural products with the alkene-substituted furan scaffold display a range of biological activities, but are difficult to access. Here, the authors report a modular biomimetic strategy to synthesise diverse alkene-substituted furan-

Heteroreceptor complexes and their allosteric receptor-receptor interactions in the central nervous system. Focus on examples from Dopamine D2 and Serotonin 5-HT1a receptors [PDF]

open access: yes, 2018
GPCR interacting proteins (specially β- arrestin) and their receptor-protein interactions are also covered but their interactions with the allosteric receptor-receptor interactions in heteroreceptor complexes remain to be elucidated.

Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]

open access: yes, 2009
We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic

Nothing Besides Remains: Preserving the Scientific and Cultural Value of Paleontological Resources in the United States [PDF]

open access: yes, 2005
Receptor occupancy assessed by Positron Emission Tomography (PET) can provide important translational information to help bridge information from one drug to another or from animal to man.

Structural determinants at the M2 muscarinic receptor modulate the RGS4-GIRK response to pilocarpine by impairment of the receptor voltage sensitivity. [PDF]

open access: yes, 2017
Membrane potential controls the response of the M2 muscarinic receptor to its ligands. Membrane hyperpolarization increases response to the full agonist acetylcholine (ACh) while decreasing response to the partial agonist pilocarpine.

A plant-derived glucocorticoid receptor modulator attenuates inflammation without provoking ligand-induced resistance [PDF]

open access: yes, 2010
Background: Acquired resistance to glucocorticoids constitutes a major clinical challenge, often overlooked in the search for improved alternatives to classic steroids.
