Interactioni
Subunit structurei
Homodimer (via N- and C-terminus); binds RNA as homodimer.
Component of the cleavage factor Im (CFIm) complex which is a heterotetramer composed of two subunits of NUDT21/CPSF5 and two subunits of CPSF6 or CPSF7 or a heterodimer of CPSF6 and CPSF7. The cleavage factor Im (CFIm) complex associates with the CPSF and CSTF complexes to promote the assembly of the core mRNA 3'-processing machinery.
Interacts with CPSF6 (via the RRM domain); this interaction is direct and enhances binding to RNA.
Interacts with CPSF7.
Interacts with FIP1L1; this interaction occurs in a RNA sequence-specific manner.
Interacts with PABPN1.
Interacts (via N-terminus) with PAPOLA (via C-terminus); this interaction is direct and diminished by acetylation.
Interacts with SNRNP70.
Interacts with VIRMA.
