Stable Protein‐Based G‐Quadruplex‐Derived Supramolecular Bioinks as Tunable ECM‐Mimetic Constructs Assembled by Combining Non‐Covalent and Covalent Strategies

Advanced Materials, EarlyView.
Harnessing the synergistic interplay of supramolecular self‐assembly, under macromolecular crowding conditions, and enzymatic‐mediated covalent crosslinking toward a stable protein‐based G‐quadruplex‐derived supramolecular bioink. This bioinspired strategy enables the biofabrication of complex and tunable ECM‐mimetic constructs, providing a platform ...

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

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

Repetitive N-WASP–binding elements of the Enterohemorrhagic Escherichia coli Effector EspFU Synergistically Activate Actin Assembly [PDF]

, 2008
Enterohemorrhagic Escherichia coli (EHEC) generate F-actin–rich adhesion pedestals by delivering effector proteins into mammalian cells. These effectors include the translocated receptor Tir, along with EspFU, a protein that associates indirectly with ...

Actin cytoskeleton in dendritic spine

Folia Pharmacologica Japonica, 2007
樹状突起スパインは脳内の主要な興奮性シナプス後部であり，その形態および構成タンパク質の可塑的変化は学習記憶などの高次機能に重要である．スパイン内の構造体としては，シナプス後部肥厚（PSD）とアクチン細胞骨格があり，スパインの形態変化は主にアクチン細胞骨格により制御されている．スパイン内ではその頭部と頸部でアクチン線維の構造が異なることに加えて，頭部の中でもシナプス直下のPSD近傍と細胞質の中心領域でアクチン結合タンパク質の分布が異なる．したがって，スパインは3種類の性質の異なるアクチン細胞骨格によって構成されていると考えられる．アクチンを脱重合させると，多くのスパイン構成タンパク質の局在が不安定化し，スパイン形態もフィロポディア様に変化する．従って，アクチン細胞骨格がスパイン形態の形成 ...

Stimuli‐Responsive Hierarchical Structuring Controls Survival and Programs Hydrogelation of Supramolecular Metallofibers

Advanced Materials, EarlyView.
Aqueous Zn(II) Salphen metallofibers decorated with PNIPAM undergo reversible, multi‐stimuli‐responsive hierarchical bundling. This higher‐order structuring kinetically stabilizes the otherwise fragile assemblies against dilution, acidic hydrolysis, and transmetallation, enables selective sorting of responsive fibers, and programs hydrogelation at ...
