Functioni

Monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin to form methionine-sulfoxide, resulting in actin filament disassembly and preventing repolymerization. In the absence of actin, it also functions as a NADPH oxidase producing H2O2 (By similarity). Acts as a cytoskeletal regulator that connects NEDD9 to intermediate filaments. Also acts as a negative regulator of apoptosis via its interaction with STK38 and STK38L; acts by antagonizing STK38 and STK38L activation by MST1/STK4. Involved in regulation of lamina-specific connectivity in the nervous system such as the development of lamina-restricted hippocampal connections. Through redox regulation of the actin cytoskeleton controls the intracellular distribution of secretory vesicles containing L1/neurofascin/NgCAM family proteins in neurons, thereby regulating their cell surface levels. May act as Rab effector protein and play a role in vesicle trafficking.By similarity4 Publications

    Caution

    The reaction mechanism is subject to discussion. Some work suggest MICAL enzymes directly oxidize actin methionine residues to produce methionine-(R)-S-oxide. Other publications suggest that the enzyme functions as a NADPH oxidase producing H2O2 (EC 1.6.3.1) and that it is the produced H2O2 that is responsible for the methionine-(R)-S-oxide production.By similarity2 Publications
