CC -!- FUNCTION: Component of the cap-binding complex (CBC), which binds CC co-transcriptionally to the 5' cap of pre-mRNAs and is involved in CC various processes such as pre-mRNA splicing, translation CC regulation, nonsense-mediated mRNA decay, RNA-mediated gene CC silencing (RNAi) by microRNAs (miRNAs) and mRNA export. The CBC CC complex is involved in mRNA export from the nucleus via its CC interaction with ALYREF/THOC4/ALY, leading to the recruitment of CC the mRNA export machinery to the 5' end of mRNA and to mRNA export CC in a 5' to 3' direction through the nuclear pore. The CBC complex CC is also involved in mediating U snRNA and intronless mRNAs export CC from the nucleus. The CBC complex is essential for a pioneer round CC of mRNA translation, before steady state translation when the CBC CC complex is replaced by cytoplasmic cap-binding protein eIF4E. The CC pioneer round of mRNA translation mediated by the CBC complex CC plays a central role in nonsense-mediated mRNA decay (NMD), NMD CC only taking place in mRNAs bound to the CBC complex, but not on CC eIF4E-bound mRNAs. The CBC complex enhances NMD in mRNAs CC containing at least one exon-junction complex (EJC) via its CC interaction with UPF1, promoting the interaction between UPF1 and CC UPF2. The CBC complex is also involved in 'failsafe' NMD, which is CC independent of the EJC complex, while it does not participate in CC Staufen-mediated mRNA decay (SMD). During cell proliferation, the CC CBC complex is also involved in microRNAs (miRNAs) biogenesis via CC its interaction with SRRT/ARS2 and is required for miRNA-mediated CC RNA interference. The CBC complex also acts as a negative CC regulator of PARN, thereby acting as an inhibitor of mRNA CC deadenylation. In the CBC complex, NCBP1/CBP80 does not bind CC directly capped RNAs (m7GpppG-capped RNA) but is required to CC stabilize the movement of the N-terminal loop of NCBP2/CBP20 and CC lock the CBC into a high affinity cap-binding state with the cap CC structure. CC -!- SUBUNIT: Component of the nuclear cap-binding complex (CBC), a CC heterodimer composed of NCBP1/CBP80 and NCBP2/CBP20 that interacts CC with m7GpppG-capped RNA. Heterodimer with NCBP2. Is part of the CC exon junction complex (EJC) containing NCBP1, NCBP2, RNPS1, RBM8A, CC SRRM1, NXF1, UPF3B, UPF2, ALYREF/THOC4 and/or REFBP2. Identified CC in a mRNP granule complex, at least composed of ACTB, ACTN4, DHX9, CC ERG, HNRNPA1, HNRNPA2B1, HNRNPAB, HNRNPD, HNRNPL, HNRNPR, HNRNPU, CC HSPA1, HSPA8, IGF2BP1, ILF2, ILF3, NCBP1, NCL, PABPC1, PABPC4, CC PABPN1, RPLP0, RPS3, RPS3A, RPS4X, RPS8, RPS9, SYNCRIP, TROVE2, CC YBX1 and untranslated mRNAs. Interacts with SRRT/ARS2, EIF4G2, CC HNRNPF, IGF2BP1, HNRNPH1, KIAA0427/CTIF, PARN, DROSHA, UPF1 and CC ALYREF/THOC4. May interact with EIF4G1; the interaction is however CC controversial (By similarity). Found in a U snRNA export complex CC with RNUXA/PHAX, NCBP1/CBP80, NCBP2/CBP20, RAN, XPO1 and m7G- CC capped RNA. Interaction with RNUXA/PHAX. CC -!- SUBCELLULAR LOCATION: Nucleus (By similarity). Cytoplasm (By CC similarity). Note=Localized in cytoplasmic mRNP granules CC containing untranslated mRNAs (By similarity). CC -!- SIMILARITY: Belongs to the NCBP1 family. CC -!- SIMILARITY: Contains 1 MIF4G domain.
