Uncoupling actin filament fragmentation by cofilin from increased subunit turnover.
The actin depolymerizing factor (ADF)/cofilin family of proteins interact with actin monomers and filaments in a pH-sensitive manner. When ADF/cofilin binds F-actin it induces a change in the helical twist and fragmentation; it also accelerates the dissociation of subunits from the pointed ends of filaments, thereby increasing treadmilling or depolymerization. Using site-directed mutagenesis we...
متن کاملXenopus actin-interacting protein 1 (XAip1) enhances cofilin fragmentation of filaments by capping filament ends.
Xenopus actin-interacting protein 1 (XAip1) is thought to promote fragmentation of actin filaments by cofilin. To examine the mechanism of XAip1, we measured polymer lengths by fluorescence microscopy and the concentration of filament ends with an elongation assay. Cofilin creates ends by severing actin filaments. XAip1 alone does not sever actin filaments or prevent annealing/redistribution of...
متن کاملTurnover of branched actin filament networks by stochastic fragmentation with ADF/cofilin
Cell motility depends on the rapid assembly, aging, severing, and disassembly of actin filaments in spatially distinct zones. How a set of actin regulatory proteins that sustains actin-based force generation during motility work together in space and time remains poorly understood. We present our study of the distribution and dynamics of Arp2/3 complex, capping protein (CP), and actin-depolymer...
متن کاملFragmentation measurement using image processing
In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...
متن کاملFragmentation Functions approach in pQCD fragmentation phenomena
Next-to-leading order parton fragmentation functions into light mesons are presented. They have been extracted from real and simulated ee data and used to predict inclusive single particle distributions at different machines. Talk given at the XXXI Rencontres de Moriond, QCD and hadronic interactions, Les Arcs, France March 24-31 1996
