ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling

open access: yesFEBS Letters, EarlyView.
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

Two Decades of Evolution of Our Understanding of the Transient Receptor Potential Melastatin 2 (TRPM2) Cation Channel

open access: yesLife, 2021
The transient receptor potential melastatin (TRPM) family belongs to the superfamily of TRP ion channels. It consists of eight family members that are involved in a plethora of cellular functions.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Modulation of Ionotropic Glutamate Receptors and Acid-Sensing Ion Channels by Nitric Oxide

open access: yesFrontiers in Physiology, 2012
Ionotropic glutamate receptors (iGluR) are ligand-gated ion channels and are densely expressed in broad areas of mammalian brains. Like iGluRs, acid-sensing ion channels (ASIC) are ligand (H+)-gated channels and are enriched in brain cells and ...

Imaging living obligate anaerobic bacteria with bilin-binding fluorescent proteins

open access: yesCurrent Research in Microbial Sciences, 2020
Fluorescent tools such as green fluorescent protein (GFP) have been used extensively as reporters in biochemistry and microbiology, but GFP and other conventional fluorescent proteins are restricted to aerobic environments.

Analyzing the Catalytic Role of Active Site Residues in the Fe-type Nitrile Hydratase from \u3cem\u3eComamonas testosteroni\u3c/em\u3e Ni1 [PDF]

open access: yes, 2015
A strictly conserved active site arginine residue (αR157) and two histidine residues (αH80 and αH81) located near the active site of the Fe-type nitrile hydratase from Comamonas testosteroni Ni1 (CtNHase), were mutated. These mutant enzymes were examined

Conformational selection in protein binding and function

open access: yes, 2014
Protein binding and function often involves conformational changes. Advanced NMR experiments indicate that these conformational changes can occur in the absence of ligand molecules (or with bound ligands), and that the ligands may 'select' protein ...

Unusual DNA binding modes for metal anticancer complexes [PDF]

open access: yes, 2009
DNA is believed to be the primary target for many metal-based drugs. For example, platinum-based anticancer drugs can form specific lesions on DNA that induce apoptosis.

Ligand-dependent structural changes and limited proteolysis of Escherichia coli phosphofructokinase-2

open access: yesArchives of Biochemistry and Biophysics, 2002
Binding of MgATP to the allosteric site of phosphofructokinase-2 promotes a dimer to tetramer conversion. In the presence of Fru-6-P the enzyme remains as a dimer. Limited proteolysis in the presence of MgATP completely protects the enzyme against inactivation and cleavage, while Fru-6-P provides a partial protection.
