CstF recognizes U and G/U-rich cis-acting RNA sequence elements and helps stabilize the Cleavage and Polyadenylation Specificity Factor (CPSF) at the polyadenylation site as required for productive RNA cleavage. Here, we describe the crystal structure of the N-terminal domain of Drosophila CstF-50 subunit. It forms a compact homodimer that exposes two geometrically opposite, identical, and conserved surfaces that may serve as binding platform. Together with previous data on the structure of CstF-77, homodimerization of CstF-50 N-terminal domain supports the model in which the functional state of CstF is a heterohexamer.
