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.

European Journal of Cell Biology, 2022 Tropomodulin and tropomyosin are important components of sarcomeric thin filaments in striated muscles. Tropomyosin decorates the side of actin filaments and enhances tropomodulin capping at the pointed ends of the filaments.

Anomalous relaxation kinetics of biological lattice-ligand binding models [PDF]
Chemical Physics, 284, 287-310 (2002), 2002 We discuss theoretical models for the cooperative binding dynamics of ligands to substrates, such as dimeric motor proteins to microtubules or more extended macromolecules like tropomyosin to actin filaments. We study the effects of steric constraints, size of ligands, binding rates and interaction between neighboring proteins on the binding dynamics ...

Birefringence of tropomyosin crystals
Biophysical Journal, 1988 The birefringence of tropomyosin crystals was measured in the temperature range 5 degrees-35 degrees C. The experimental results are compared with a simple model calculation based on the theory developed by Wiener for the optical properties of colloidal systems.

Tropomyosin autoantibodies associated with checkpoint inhibitor myositis
OncoImmunology, 2020 This brief report details the measurement and identification of IgA antibodies to tropomyosin in a case of presumed ocular myositis with paraspinal myositis in a patient with metastatic uveal melanoma treated with checkpoint inhibitors.

iScience, 2022 Summary: The effects of N-terminal acetylation of the high molecular weight tropomyosin isoforms Tpm1.6 and Tpm2.1 and the low molecular weight isoforms Tpm1.12, Tpm3.1, and Tpm4.2 on the actin affinity and the thermal stability of actin-tropomyosin ...

Foods, 2023 Tropomyosin (TM) is the major allergen of shrimp (Penaeus chinensis). Previous studies showed that separate cold plasma or glycation have their drawback in reducing allergenicity of TM, including effectiveness and reliability. In the current study, a new

Tropomyosin antibody: the specific localization of tropomyosin in nonmuscle cells. [PDF]
The Journal of cell biology, 1975 An antibody against purified chicken skeletal muscle tropomyosin is used in indirect immunofluorescence to visualize the localization of tropomyosin in a variety of nonmuscle cells. The antibody produces a fluorescent pattern which is very similar to that obtained with an actin-specific antibody. This pattern is composed of fluorescent fibers which are

Distortion of the Actin A-Triad Results in Contractile Disinhibition and Cardiomyopathy
Cell Reports, 2017 Striated muscle contraction is regulated by the movement of tropomyosin over the thin filament surface, which blocks or exposes myosin binding sites on actin.
