| Short Name | MICAL3 |
| description | MICAL (molecule Interacting with CasL) family is a group of multifunctional proteins that contain the calponin homology (CH), a LIM and a coiled-coil (CC) domains []. They interact with receptors on the target cells, help recruiting other proteins, and promote the modulation of their activity with respect to the downstream events []. There is only one MICAL protein found in Drosophila [], while there are 5 MICAL (MICAL1/2/3, MICAL-like1/2) isoforms found in vertebrates []. Drosophila MICAL and vertebrate MICAL1/2/3 contain an extra N-terminal FAD (flavin adenine dinucleotide binding monooxygenase) domain, whose structure resembles that of a flavo-enzyme, p-hydroxybenzoate hydroxylase []. Drosophila MICAL has an NADPH-dependent actin depolymerising activity []. Vertebrate MICALs are also shown to be effectors of small Rab GTPases, which play important roles in vesicular trafficking []. This entry represents MICAL3. MICAL3 links Rab8A and ELKS (a Rab6-interacting cortical factor). The FAD domain of MICAL3 is required to regulate its own turnover and the associated remodelling of vesicle-docking protein complexes []. Also included in MICAL1 from Danio rerio, which is thought to be an [F-actin]-methionine sulfoxide oxidase. |
