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
