Cysteine-rich protein 2 accelerates actin filament cluster formation. [PDF]

open access: yesPLoS ONE, 2017
Filamentous actin (F-actin) forms many types of structures and dynamically regulates cell morphology and movement, and plays a mechanosensory role for extracellular stimuli. In this study, we determined that the smooth muscle-related transcription factor,

Order and disorder in intermediate filament proteins [PDF]

open access: yesFEBS Letters, 2015
Intermediate filaments (IFs), important components of the cytoskeleton, provide a versatile, tunable network of self‐assembled proteins. IF proteins contain three distinct domains: an α‐helical structured rod domain, flanked by intrinsically disordered head and tail domains.

Deimination, Intermediate Filaments and Associated Proteins [PDF]

open access: yesInternational Journal of Molecular Sciences, 2020
Deimination (or citrullination) is a post-translational modification catalyzed by a calcium-dependent enzyme family of five peptidylarginine deiminases (PADs). Deimination is involved in physiological processes (cell differentiation, embryogenesis, innate and adaptive immunity, etc.) and in autoimmune diseases (rheumatoid arthritis, multiple sclerosis ...

The recruitment of acetylated and unacetylated tropomyosin to distinct actin polymers permits the discrete regulation of specific myosins in fission yeast. [PDF]

open access: yes, 2010
Tropomyosin (Tm) is a conserved dimeric coiled-coil protein, which forms polymers that curl around actin filaments in order to regulate actomyosin function.

Biochemical characterization of actin assembly mechanisms with ALS-associated profilin variants

open access: yesEuropean Journal of Cell Biology, 2022
Eight separate mutations in the actin-binding protein profilin-1 have been identified as a rare cause of amyotrophic lateral sclerosis (ALS). Profilin is essential for many neuronal cell processes through its regulation of lipids, nuclear signals, and ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Stabilization of the cortical cytoskeleton by the lipid raft-associated protein cap23 [PDF]

open access: yes, 2006
In the present work, we identified the lipid raft-associated protein Cap23 to be involved in several important neuronal functions like the organization of lipid raft platforms, the maturation and stabilization of the actin- and intermediate filament ...

The Effects of Hsp90α1 Mutations on Myosin Thick Filament Organization. [PDF]

open access: yesPLoS ONE, 2015
Heat shock protein 90α plays a key role in myosin folding and thick filament assembly in muscle cells. To assess the structure and function of Hsp90α and its potential regulation by post-translational modification, we developed a combined knockdown and ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

open access: yesFEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Organized unidirectional waves of ATP hydrolysis within a RecA filament.

open access: yesPLoS Biology, 2005
The RecA protein forms nucleoprotein filaments on DNA, and individual monomers within the filaments hydrolyze ATP. Assembly and disassembly of filaments are both unidirectional, occurring on opposite filament ends, with disassembly requiring ATP ...
