Also, by using preformed pyrene F-actin, it is possible to follow depolymerization. Both cell/tissue extracts and purified proteins can be added to the reaction mixture to identify their effect on actin polymerization. The components of the kit can also be used separately for other actin based ...

The Actin Polymerization Biochem Kit™ is based on the enhanced fluorescence of pyrene conjugated actin that occurs during polymerization. The enhanced fluorescence that occurs when pyrene G-actin (monomer) forms pyrene F-actin can be measured in a fluorimeter to follow polymerization over time. Al...

Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of a two-stranded helix. Each actin can bind to 4 others. Identified in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL...
To test the effect of THz irradiation on the elongation of actin filaments, 1.2 μM actin solution was subjected to the polymerization reaction for 1 h without THz irradiation and induced into the steady state, in which elongation and depolymerization of actin filaments were equilibrated. ...
Polymerization of globular actin (G-actin) leads to a structural filament (F-actin) in the form of a two-stranded helix. Each actin can bind to 4 others. Subcellular Location: Cytoplasm, cytoskeleton. Post-translational modifications: Oxidation of Met-46 by MICALs (MICAL1, MICAL2 or MICAL...
Both are processes relying on functional actin polymerization and depolymerization64,65. In addition, we identified other proteins bound to actin rods (Supplementary Table 1). Several of them such as peroxiredoxin1, annexin2 or 14–3–3 were already identified in an earlier study analyzing actin ...
In this short review, we will survey the principles ofactin polymerizationthat are used by different actinbinding proteinseither to regulate actin desequestration, thus eliciting massive assembly of filaments, or to controlactin filamentturnover, thus mediating the forward movement of the leading edge....
