Connexin domains relevant to the chemical gating of gap junction channels
Most cells exchange ions and small metabolites via gap junction channels. These channels are made of two hemichannels (connexons), each formed by the radial arrangement of six connexin (Cx) proteins. Connexins span the bilayer four times (M1-M4) and have

Can calmodulin bind to lipids of the cytosolic leaflet of plasma membranes?
Calmodulin (CaM) is a ubiquitous calcium-sensitive messenger in eukaryotic cells. It was previously shown that CaM possesses an affinity for diverse lipid moieties, including those found on CaM-binding proteins. These facts, together with our observation

Ion Activation Methods for Top‐Down Proteomics
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Small‐Molecule Kinase Inhibitors Modulating Circadian Rhythms
ABSTRACT The circadian clock mechanism generates 24‐h rhythms crucial for regulating various physiological processes, and its dysregulation has been implicated in numerous diseases. In cells, the circadian clock operates through a transcriptional‐translational feedback loop, where phosphorylation plays a pivotal role in maintaining accurate circadian ...
