Crystal Structure of the C-Terminal Half of Tropomodulin and Structural Basis of Actin Filament Pointed-End Capping

open access: yes, 2002
Tropomodulin is the unique pointed-end capping protein of the actin-tropomyosin filament. By blocking elongation and depolymerization, tropomodulin regulates the architecture and the dynamics of the filament.

Role of active contraction and tropomodulins in regulating actin filament length and sarcomere structure in developing zebrafish skeletal muscle

open access: yesFrontiers in Physiology, 2016
Whilst it is recognised that contraction plays an important part in maintaining the structure and function of mature skeletal muscle, its role during development remains undefined.

Aspartame Increases the Risk of Pancreatic Ductal Adenocarcinoma

open access: yeseFood, Volume 7, Issue 3, June 2026.
Aspartame (APM) is a widely used artificial sweetener associated with various health concerns, including potential links to diabetes, cardiovascular diseases, and an increased risk of cancer. A comprehensive approach incorporating data mining, machine learning, network toxicology, molecular docking, molecular dynamics simulations, and clinical sample ...

Innate immunity shapes the persistent transmission of plant viruses by insect vectors

open access: yesNew Plant Protection, Volume 3, Issue 2, June 2026.
In this review, we focus on two key aspects of the virus–vector interplay: (1) persistently transmitted viruses utilize host factors to overcome transmission barriers; and (2) molecular recognition activates antiviral immunity and subsequent viral counter‐defense. Understanding these interactions offers critical insights for developing novel strategies

The multifaceted roles of the ACSL family in cancer: Metabolic reprogramming, ferroptosis regulation and tumour immune microenvironment remodelling

open access: yesClinical and Translational Medicine, Volume 16, Issue 3, March 2026.
The acyl‐CoA synthetase long‐chain (ACSL) family consists of five members, which exhibit a synergistic effect in promoting tumour lipid metabolism for energy supply. Specifically, ACSL3 and ACSL4 have antagonistic effects on the mechanisms related to ferroptosis in tumour cells.

Mechanism of actin filament pointed-end capping by tropomodulin [PDF]

open access: yesScience, 2014
Making tropomodulin find the right point Actin filaments are a key component of the cell's cytoskeleton. Actin filaments have a characteristic polarized architecture with a so-called barbed end and a pointed end—so described because of how the filaments look under the electron microscope when they are coated with tropomyosin.

Alteration of Tropomyosin-binding Properties of Tropomodulin-1 Affects Its Capping Ability and Localization in Skeletal Myocytes

open access: yes, 2013
Tropomodulin (Tmod) is an actin-capping protein that binds to the two tropomyosins (TM) at the pointed end of the actin filament to prevent further actin polymerization and depolymerization.

The shapes and sizes of two domains of tropomodulin, the P-end-capping protein of actin-tropomyosin

open access: yes, 2001
Tropomodulin, the P-end (slow-growing end)-capping protein of the actin-tropomyosin filament, and its fragment (C20) of the C-terminal half were studied by synchrotron small-angle X-ray scattering, restoring low-resolution shapes using an ab initio shape-

Super-Resolution Microscopy Reveals the Native Ultrastructure of the Erythrocyte Cytoskeleton

open access: yesCell Reports, 2018
Summary: The erythrocyte cytoskeleton is a textbook prototype for the submembrane cytoskeleton of metazoan cells. While early experiments suggest a triangular network of actin-based junctional complexes connected by ∼200-nm-long spectrin tetramers, later

Evolution of Plasticity in Response to Ethanol Between Recently Separated Populations of D. melanogaster With Different Ecological Histories

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
We identified: (1) differences in gene expression among each locale; (2) changes in gene expression in response to treatment; (3) genotype‐specific changes in gene expression in response to treatment. ABSTRACT While there is abundant theoretical work on the evolution of phenotype plasticity, empirical support has lagged.
