Isoform Specificity of a Compound Targeting Actin Filaments Containing Tropomyosin Tpm1.8/1.9
Cytoskeleton, EarlyView.ABSTRACT The unbranched actin filaments in mammalian cells are usually composed of co‐polymers of a specific tropomyosin isoform with actin. Genetic manipulation has revealed that the tropomyosins largely define the functional properties of actin filaments in an isoform‐specific, non‐redundant manner.

Frontiers in PhysicsAt low free Ca2+, the actin binding proteins tropomyosin, troponin I, troponin T and troponin C inhibit contraction in striated muscles. Ca2+ activation alters the position of tropomyosin on actin to uncover binding sites for high affinity forms of ...

Frontiers in Cell and Developmental Biology, 2020 The calponin homology (CH) domain is one of the most common modules in various actin-binding proteins and is characterized by an α-helical fold. The CH domain plays important regulatory roles in both cytoskeletal dynamics and signaling.

Children, 2023 (1) Background: Tropomyosin is a major cause of shellfish allergy and anaphylaxis triggered by food. It acts as a pan-allergen, inducing cross-reactivity in insects, dust mites, crustaceans, and mollusks.

Equilibrium self‐association of tropomyosin [PDF]
FEBS Letters, 2012 It has recently been reported that tropomyosin exists exclusively as a dimer in physiological salt conditions. It is shown in the present work using analytical ultracentrifugation that, on the contrary, tropomyosin is in equilibrium between monomer, dimer and tetramer with a weak tendency to dimerize and tetramerize. Such a finding has consequences for

Food Frontiers, EarlyView.Edible insects offer a sustainable protein source, requiring fewer resources than traditional livestock. Despite challenges, they have the potential to enhance food security and sustainability for a growing global population. ABSTRACT As the world faces an escalating protein crisis amid climate change, population growth, and resource scarcity, edible ...

Interaction of actin with dansyl‐tropomyosin [PDF]
FEBS Letters, 1986 5‐[Dimethylamino]naphthalene‐1‐sulfonyl chloride (dansyl chloride) reacts with rabbit skeletal muscle tropomyosin (TM) to yield a highly fluorescent product, DNS‐TM. The extent of modification of TM can be regulated over a wide range, 0.3–15.5 dansyl groups per TM, depending upon the temperature and duration of the reaction.

Changing of expression actinbinding proteins in the kidney under dehydration
Вавиловский журнал генетики и селекции, 2018 Actin is related to main structural proteins in eukaryotes. In opposite to muscle alpha-actin, beta-actin is expressing in all types of cells. The constant reorganization of actin cytoskeleton takes place in non-muscle cells.

Dynamics of tropomyosin in muscle fibers as monitored by saturation transfer EPR of bi-functional probe. [PDF]
PLoS ONE, 2011 The dynamics of four regions of tropomyosin was assessed using saturation transfer electron paramagnetic resonance in the muscle fiber. In order to fully immobilize the spin probe on the surface of tropomyosin, a bi-functional spin label was attached to ...
