The cwf21 family is involved in mRNA splicing. 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.
The cwf21 domain is found in proteins involved in mRNA splicing. Proteins containing this domain have been isolated as a subcomplex of the splicosome in Schizosaccharomyces pombe (Fission yeast) [PUBMED:11884590]. In yeast, this domain binds the protein Prp8p [PUBMED:19854871], a large and highly conserved U5 snRNP protein which has been proposed as a protein cofactor at the spliceosomal catalytic centre [PUBMED:11017191].
