Effects of Antipsychotic Administration on Brain Glutamate in Schizophrenia: A Systematic Review of Longitudinal 1H-MRS Studies

open access: yesFrontiers in Psychiatry, 2017
Schizophrenia is associated with brain glutamate dysfunction, but it is currently unclear whether antipsychotic administration can reduce the extent of glutamatergic abnormality. We conducted a systematic review of proton magnetic resonance spectroscopy (

Synthesis and photochemical reactivity of caged glutamates with a π-​extended coumarin chromophore as a photolabile protecting group [PDF]

open access: yes, 2013
International audience'Caging' and 'uncaging' bioactive substrates are key techniques in studying a wide variety of biological processes. In the present study, two-types of novel caged glutamates with a two-photon absorption (TPA) core, that is, π ...

Acidic amino acids in the first intracellular loop contribute to voltage- and calcium- dependent gating of anoctamin1/TMEM16A. [PDF]

open access: yesPLoS ONE, 2014
Anoctamin1 (Ano1, or TMEM16A) is a Ca2+-activated chloride channel that is gated by both voltage and Ca2+. We have previously identified that the first intracellular loop that contains a high density of acidic residues mediates voltage- and calcium ...

Cytosolic Carboxypeptidase 5 Removes α- and γ-Linked Glutamates from Tubulin*

open access: yesJournal of Biological Chemistry, 2013
Background: Cytosolic carboxypeptidase 5 (CCP5) was proposed to selectively cleave γ-linked glutamate from tubulin side chains, but not α-linked glutamates. Results: Purified CCP5 removes α- and γ-linked glutamates from microtubules, soluble tubulin, and

Structural insights into the electron/proton transfer pathways in the quinol:fumarate reductase from Desulfovibrio gigas [PDF]

open access: yes, 2018
The membrane-embedded quinol:fumarate reductase (QFR) in anaerobic bacteria catalyzes the reduction of fumarate to succinate by quinol in the anaerobic respiratory chain. The electron/proton-transfer pathways in QFRs remain controversial.

The unanticipated complexity of the selectivity-filter glutamates of nicotinic receptors

open access: yesNature Chemical Biology, 2012
In ion channels, “rings” of ionized side chains that decorate the walls of the permeation pathway often lower the energetic barrier to ion conduction.

Vicinal glutamates are better phosphomimetics: Phosphorylation is required for allosteric activation of guanylyl cyclase-A

open access: yesFrontiers in Molecular Neuroscience, 2022
Multisite phosphorylation of guanylyl cyclase (GC)-A, also known as NPR-A or NPR1, is required for receptor activation by natriuretic peptides (NPs) because alanine substitutions for the first four GC-A phosphorylation sites produce an enzyme that cannot

Liquid droplet formation by HP1α suggests a role for phase separation in heterochromatin. [PDF]

open access: yes, 2017
Gene silencing by heterochromatin is proposed to occur in part as a result of the ability of heterochromatin protein 1 (HP1) proteins to spread across large regions of the genome, compact the underlying chromatin and recruit diverse ligands.

Glutamate and Epilepsy [PDF]

open access: yesThe Journal of Nutrition, 2000
Epileptic syndromes have very diverse primary causes, which may be genetic, developmental or acquired. In rodent models, altering glutamate receptor or glutamate transporter expression by knockout or knockdown procedures can induce or suppress epileptic seizures.

A structural and functional model for human bone sialoprotein [PDF]

open access: yes, 2012
Human bone sialoprotein (BSP) is an essential component of the extracellular matrix of bone. It is thought to be the primary nucleator of hydroxyapatite crystallization, and is known to bind to hydroxyapatite, collagen, and cells.
