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 (PubMed:9659921, PubMed:8626397, PubMed:14561889, PubMed:20695905, PubMed:23187700). The cleavage factor Im (CFIm) complex associates with the CPSF and CSTF complexes to promote the assembly of the core mRNA 3'-processing machinery (PubMed:29276085). Associates with the exon junction complex (EJC) (PubMed:19864460). Associates with the 80S ribosome particle (PubMed:19864460). Interacts (via the RRM domain) with NUDT21/CPSF5; this interaction is direct and enhances binding to RNA (PubMed:14561889, PubMed:15169763, PubMed:19864460, PubMed:29276085, PubMed:21295486). Interacts (via Arg/Ser-rich domain) with FIP1L1 (preferentially via unphosphorylated form and Arg/Glu/Asp-rich domain); this interaction mediates, at least in part, the interaction between the CFIm and CPSF complexes and may be inhibited by CPSF6 hyper-phosphorylation (PubMed:29276085). Interacts (via N-terminus) with NXF1; this interaction is direct (PubMed:19864460). Interacts with SRSF3 (PubMed:15169763). Interacts with SRSF7 (PubMed:15169763). Interacts with SNRNP70 (PubMed:14561889). Interacts with TRA2B/SFRS10 (PubMed:15169763). Interacts with UPF1 (PubMed:19864460). Interacts with UPF3B (PubMed:19864460). Interacts with VIRMA (PubMed:29507755). Interacts (via Arg/Ser-rich domain) with TNPO3; promoting nuclear import of CPSF6 independently of its phosphorylation status (PubMed:30916345). Interacts with YTHDC1 (By similarity). (Microbial infection) Interacts (via C-terminus) with HIV-1 capsid protein p24 (CA).
