Is predicted to encode a protein with the following domains: Cleavage stimulation factor subunit 1, dimerisation domain; WD domain, G-beta repeat; CSTF1, dimerization domain superfamily; WD40 repeat; WD40/YVTN repeat-like-containing domain superfamily; and WD40-repeat-containing domain superfamily. Is an ortholog of C. elegans cpf-1.
