An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Effects of streptozotocin-induced diabetes on neural sigma receptors in the rat brain [PDF]

open access: yes, 1999
To study the effect of diabetes mellitus on the density of sigma receptors, in vitro binding experiments were conducted in whole brain homogenate membranes of 5-week and 10-week control rats and streptozotocin (STZ)-induced diabetic rats.

Biochemical Pharmacology of the Sigma-1 Receptor [PDF]

open access: yesMolecular Pharmacology, 2016
The sigma-1 receptor (S1R) is a 223 amino acid two transmembrane (TM) pass protein. It is a non-ATP-binding nonglycosylated ligand-regulated molecular chaperone of unknown three-dimensional structure. The S1R is resident to eukaryotic mitochondrial-associated endoplasmic reticulum and plasma membranes with broad functions that regulate cellular calcium

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Structural and Biochemical Investigations of Sigma Receptors [PDF]

open access: yes, 2019
The sigma-1 and sigma-2 receptors are a pair of enigmatic membrane proteins that are promising drug targets for the treatment of several conditions. Ligands targeting the sigma-1 receptor may be useful for the treatment of neuropathic pain, ischemic ...

Potentiation of nerve growth factor-induced neurite outgrowth in PC12 cells by ifenprodil: the role of sigma-1 and IP3 receptors.

open access: yesPLoS ONE, 2012
In addition to both the α1 adrenergic receptor and N-methyl-D-aspartate (NMDA) receptor antagonists, ifenprodil binds to the sigma receptor subtypes 1 and 2.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Sigma-1 receptors: potential therapeutic targets for substance use disorders [PDF]

open access: yes, 2019
Substance use disorders are a prominent issue within the United States that must be addressed given the high prevalence, economic cost, and negative health consequences of these medical conditions.

In vitro and ex vivo characterization of sigma-1 and sigma-2 receptors: agonists and antagonists in biological assays [PDF]

open access: yes, 2009
Methods for addressing sigma receptor affinity and activity have been explored and although several protocols have been employed, only few procedures resulted reliable.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

open access: yesFEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.
