MICAL1 (Molecule Interacting with CasL 1) is a cytosolic protein belonging to the MICAL family, which plays critical roles in regulating cytoskeletal dynamics, particularly actin filament organization. Initially identified through its interaction with the cytoplasmic domain of semaphorin receptors, MICAL1 is characterized by an N-terminal flavin monooxygenase-like domain, a central coiled-coil region, and a C-terminal conserved domain. Its enzymatic activity, mediated by the flavin-binding monooxygenase domain, facilitates redox-dependent destabilization of actin filaments via post-translational modification. This process is essential for actin cytoskeleton remodeling during cell migration, vesicle trafficking, and axonal guidance.
MICAL1 interacts with multiple signaling molecules, including Rab GTPases and components of the Semaphorin-Plexin pathway, bridging extracellular cues to intracellular cytoskeletal rearrangements. It is expressed in diverse tissues, with prominent roles in neuronal development, muscle cell organization, and immune cell function. Dysregulation of MICAL1 has been linked to pathological conditions such as cancer metastasis (promoting invasive cell behavior), neurodegenerative disorders (through aberrant axon pruning), and cardiovascular diseases (affecting vascular remodeling). Recent studies also highlight its potential as a therapeutic target due to its unique enzymatic mechanism. Structural and functional studies continue to explore how MICAL1’s multi-domain architecture coordinates its redox signaling with cytoskeletal regulation across cellular contexts.
