G-actin and f-actin
Did you know?
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm. An actin protein is the monomeric subunit of two types of filaments in cells: micr… WebSuppose you have recently isolated two cytosolic actin-associated proteins, referred to as "A" and "B", you suspect are f-actin capping proteins. To investigate whether this is true, you perform actin assembly reactions using purified fluorescent g-actin. In this protocol, you first form solid green f-actin using GFP-actin in the absence of the ...
Webcontaining either G-actin or F-actin was determined using the Bradford protein assay (Bio-Rad, Hercules, CA, USA), and the separated actin contents were analysed by immunoblotting. The F-actin to G-actin ratio was calculated by dividing the F-actin density regulated by the G-actin binding, and is expressed as a percentage of that in the control ...
