Catastrophic disassembly of actin filaments via Mical-mediated oxidation. [PDF]
, 2017 Actin filament assembly and disassembly are vital for cell functions. MICAL Redox enzymes are important post-translational effectors of actin that stereo-specifically oxidize actin's M44 and M47 residues to induce cellular F-actin disassembly.
