Connexin domains relevant to the chemical gating of gap junction channels

Brazilian Journal of Medical and Biological Research, 1997
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?

Open Biology
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

Purification of Calmodulin-Stimulated Phosphodiesterase by Affinity-Chromatography on Calmodulin Fragment-1-77 Linked to Sepharose

, 1988
Because of the presence of many calmodulin-binding proteins in brain, affinity chromatography based on binding to calmodulin lacks specificity. Additional conventional purification steps are needed, prolonging the length of the purification procedure ...

Alcohols increase calmodulin affinity for Ca2+ and decrease target affinity for calmodulin [PDF]

, 2004
It has been proposed that alcohols and anesthetics selectively inhibit proteins containing easily disrupted motifs, e.g., α-helices. In this study, the calcineurin/calmodulin/Ca2+ enzyme system was used to examine the effects of alcohols on calmodulin, a

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

The Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Stimulus–Transcription Coupling of TRPM3 Channels: A Signaling Pathway from the Plasma Membrane to the Nucleus

Biomolecules
Transient receptor potential melastatin-3 (TRPM3) channels are cation channels activated by heat and chemical ligands. TRPM3 regulates heat sensation, secretion, neurotransmitter release, iris constriction, and tumor promotion.

IgG Glycosylation‐Dependent CLEC7A Signaling Drives Podocyte Dysfunction in Lupus Nephritis

Arthritis &Rheumatology, EarlyView.
Objective Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE) that can lead to end‐stage kidney disease and increased mortality. IgG from patients with LN displays abnormal glycosylation, contributing to podocyte injury.

Homologous membrane wrapped ZIF‐8 nanoparticles accelerate differentiation of neural stem cell for spinal cord injury therapy

BMEMat, EarlyView.
Homologous membrane wrapped ZIF‐8 nanoparticles were proposed to improve biocompatibility and targeting ability to neural stem cells (NSCs). ZIF‐8‐SCM NPs exhibit pH responsiveness, thereby generating an intracellular Zn2+ storm to accelerate neural differentiation through calcium and MAPK signaling pathways. Moreover, they promote function recovery in
