| + | [https://www.uniprot.org/uniprot/MICA1_MOUSE MICA1_MOUSE] Monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin. Acts by modifying actin subunits through the addition of oxygen to form methionine-sulfoxide, leading to promote actin filament severing and prevent repolymerization. Acts as a cytoskeletal regulator that connects NEDD9 to intermediate filaments (By similarity). 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. | ||

During development, neurons are guided to their targets by short- and long-range attractive and repulsive cues. MICAL, a large multidomain protein, is required for the combined action of semaphorins and plexins in axon guidance. Here, we present the structure of the N-terminal region of MICAL (MICAL(fd)) determined by x-ray diffraction to 2.0 A resolution. The structure shows that MICAL(fd) is an FAD-containing module structurally similar to aromatic hydroxylases and amine oxidases. In addition, we present biochemical data that show that MICAL(fd) is a flavoenzyme that in the presence of NADPH reduces molecular oxygen to H(2)O(2) (K(m,NAPDH) = 222 microM; k(cat) = 77 sec(-1)), a molecule with known signaling properties. We propose that the H(2)O(2) produced by this reaction may be one of the signaling molecules involved in axon guidance by MICAL. | During development, neurons are guided to their targets by short- and long-range attractive and repulsive cues.
