Genomic organization of Tropomodulins 2 and 4 and unusual intergenic and intraexonic splicing of YL-1 and Tropomodulin 4 [PDF]

open access: yesBMC Genomics, 2001
Background The tropomodulins (TMODs) are a family of proteins that cap the pointed ends of actin filaments. Four TMODs have been identified in humans, with orthologs in mice.

Mutations changing tropomodulin affinity for tropomyosin alter neurite formation and extension [PDF]

open access: yesPeerJ, 2013
Assembly of the actin cytoskeleton is an important part of formation of neurites in developing neurons. Tropomodulin, a tropomyosin-dependent capping protein for the pointed end of the actin filament, is one of the key players in this process ...

Folding Properties of Functional Domains of Tropomodulin [PDF]

open access: yesBiophysical Journal, 2001
Tropomodulin (Tmod) stabilizes the actin-tropomyosin filament by capping the slow-growing end (P-end). The N- and C-terminal halves play distinct roles; the N-terminal half interacts with the N-terminal region of tropomyosin, whereas the C-terminal half interacts with actin. Our previous study (A.

Leiomodin and tropomodulin in smooth muscle [PDF]

open access: yesAmerican Journal of Physiology-Cell Physiology, 2001
Evidence is accumulating to suggest that actin filament remodeling is critical for smooth muscle contraction, which implicates actin filament ends as important sites for regulation of contraction. Tropomodulin (Tmod) and smooth muscle leiomodin (SM-Lmod) have been found in many tissues containing smooth muscle by protein immunoblot and ...

Gene Assignment, Expression, and Homology of Human Tropomodulin

open access: yesGenomics, 1996
Tropomodulin is a newly characterized pointed end capping protein for actin filaments. It binds specifically to the N terminus of tropomyosin and blocks the elongation and depolymerization of tropomyosin-coated actin filaments. A 1.9-kb human tropomodulin cDNA clone was used to map its gene by fluorescence in situ hybridization.

Tropomodulins and tropomyosins – organizers of cellular microcompartments

open access: yesBiomolecular Concepts, 2013
Eukaryotic cells show a remarkable compartmentalization into compartments such as the cell nucleus, the Golgi apparatus, the endoplasmic reticulum, and endosomes.

N-tropomodulin: A novel isoform of tropomodulin identified as the major binding protein to brain tropomyosin

open access: yesJournal of Cell Science, 1996
ABSTRACT We have identified and characterized two proteins in rat brain that bind to the neuron-specific tropomyosin isoform, TMBr3. The two proteins were identified by blot overlay assay, in which the proteins immobilized on the membrane were probed by epitope-tagged TMBr3, followed by detection with anti-epitope antibody.

Cardiac leiomodin2 binds to the sides of actin filaments and regulates the ATPase activity of myosin. [PDF]

open access: yesPLoS ONE, 2017
Leiomodin proteins are vertebrate homologues of tropomodulin, having a role in the assembly and maintenance of muscle thin filaments. Leiomodin2 contains an N-terminal tropomodulin homolog fragment including tropomyosin-, and actin-binding sites, and a C-

Tropomodulin’s Actin-Binding Abilities Are Required to Modulate Dendrite Development [PDF]

open access: yesFrontiers in Molecular Neuroscience, 2018
There are many unanswered questions about the roles of the actin pointed end capping and actin nucleation by tropomodulins (Tmod) in regulating neural morphology.

Leiomodin creates a leaky cap at the pointed end of actin-thin filaments.

open access: yesPLoS Biology, 2020
Improper lengths of actin-thin filaments are associated with altered contractile activity and lethal myopathies. Leiomodin, a member of the tropomodulin family of proteins, is critical in thin filament assembly and maintenance; however, its role is under
