This domain is found towards the N terminus of a group of animal of monooxygenases that play a crucial role in the regulation of the actin cytoskeleton. These enzymes promote the depolymerisation of F-actin by oxidising specific methionine residues on actin, leading to the formation of methionine -sulfoxide, which results in actin filament disassembly and prevents repolymerisation. This domain adopts a Rossman fold.	Domain

The CH domain is found in both cytoskeletal proteins and signal transduction proteins [1]. The CH domain is involved in actin binding in some members of the family. However in calponins there is evidence that the CH domain is not involved in its actin binding activity [4]. Most member proteins have from two to four copies of the CH domain, however some proteins such as calponin and Swiss:P15498 have only a single copy.	Domain
A	PF01494	FAD binding domain (FAD_binding_3)	FAD binding domain	This domain is involved in FAD binding in a number of enzymes.	Domain
