MICAL3
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. Involved in exocytic vesicles tethering and fusion: the monooxygenase activity is required for this process.

Single cell type specificity
Cell type enhanced (Oligodendrocytes, Excitatory neurons, Inhibitory neurons)
Immune cell specificity
Immune cell enriched (basophil)
Cell line specificity

Interaction
Interacts with RAB1B, RAB8A, RAB10, RAB13 and RAB15 (in their GTP-bound forms); binding to RAB1B is of low affinity compared to other Rab proteins; at least in case of RAB8A can bind 2 molecules of RAB8A simultaneously through a high and a low affinity binding site, respectively. Interacts with ERC1 and RAB8A; may bridge ERC1 with RAB8A. Interacts with KIF23 and ERC1; enhances the interaction between KIF23 and ERC1. Interacts with NINL isoform 2.
