The function of Ensembl gene identifier ENSG00000133816 (MICAL2, microtubule associated monooxygenase, calponin and LIM domain containing 2) is as follows. Methionine monooxygenase that promotes depolymerization of F- actin by mediating oxidation of residues 'Met-44' and 'Met-47' on actin to form methionine-sulfoxide, resulting in actin filament disassembly and preventing repolymerization (PubMed:24440334, PubMed:29343822). Regulates the disassembly of branched actin networks also by oxidizing ARP3B-containing ARP2/3 complexes leading to ARP3B dissociation from the network (PubMed:34106209). Acts as a key regulator of the SRF signaling pathway elicited by nerve growth factor and serum: mediates oxidation and subsequent depolymerization of nuclear actin, leading to increase MKL1/MRTF-A presence in the nucleus and promote SRF:MKL1/MRTF- A-dependent gene transcription. Does not activate SRF:MKL1/MRTF-A through RhoA (PubMed:24440334). {ECO:0000269|PubMed:24440334, ECO:0000269|PubMed:29343822, ECO:0000269|PubMed:34106209}.
