It has been isolated as a subcomplex of the splicosome in Schizosaccharomyces pombe [1]. The function of the cwf21 domain is to bind directly to the spliceosomal protein Prp8. Mutations in the cwf21 domain prevent Prp8 from binding [2]. The structure of this domain has recently been solved which shows this domain to be composed of two alpha helices.	Domain
