WebSep 2, 1997 · This mutant protein binds weakly to both G- and F-actin. zmadf3–2 has the tyrosines at positions 67 and 70, each replaced by phenylalanine. zmadf3–2 binds G-actin in a similar manner to maize ADF3, but does not bind F-actin. Both mutant proteins inhibit the assembly and disassembly of actin as compared with maize ADF3. WebSep 26, 2016 · The cortex is a thin network of actin that lies under and is tethered to the plasma membrane in most animal cells. Cortical actin filaments are organized in a meshwork crosslinked by specific proteins and by myosin motors, which generate contractile stresses in the network ( Clark et al., 2014 ).
