Genes affected

MICAL1 (HGNC:20619): (microtubule associated monooxygenase, calponin and LIM domain containing 1) This gene encodes an enzyme that oxidizes methionine residues on actin, thereby promoting depolymerization of actin filaments. This protein interacts with and regulates signalling by NEDD9/CAS-L (neural precursor cell expressed, developmentally down-regulated 9). Alternative splicing results in multiple transcript variants.
