CC -!- FUNCTION: Component of the cap-binding complex (CBC), which binds
CC cotranscriptionally to the 5'-cap of pre-mRNAs and is involved in
CC various processes such as pre-mRNA splicing, translation regulation,
CC nonsense-mediated mRNA decay, RNA-mediated gene silencing (RNAi) by
CC microRNAs (miRNAs) and mRNA export. The CBC complex is involved in mRNA
CC export from the nucleus via its interaction with ALYREF/THOC4/ALY,
CC leading to the recruitment of the mRNA export machinery to the 5'-end
CC of mRNA and to mRNA export in a 5' to 3' direction through the nuclear
CC pore. The CBC complex is also involved in mediating U snRNA and
CC intronless mRNAs export from the nucleus. The CBC complex is essential
CC for a pioneer round of mRNA translation, before steady state
CC translation when the CBC complex is replaced by cytoplasmic cap-binding
CC protein eIF4E. The pioneer round of mRNA translation mediated by the
CC CBC complex plays a central role in nonsense-mediated mRNA decay (NMD),
CC NMD only taking place in mRNAs bound to the CBC complex, but not on
CC eIF4E-bound mRNAs. The CBC complex enhances NMD in mRNAs containing at
CC least one exon-junction complex (EJC) via its interaction with UPF1,
CC promoting the interaction between UPF1 and UPF2. The CBC complex is
CC also involved in 'failsafe' NMD, which is independent of the EJC
CC complex, while it does not participate in Staufen-mediated mRNA decay
CC (SMD). During cell proliferation, the CBC complex is also involved in
CC microRNAs (miRNAs) biogenesis via its interaction with SRRT/ARS2 and is
CC required for miRNA-mediated RNA interference. The CBC complex also acts
CC as a negative regulator of PARN, thereby acting as an inhibitor of mRNA
CC deadenylation. In the CBC complex, NCBP1/CBP80 does not bind directly
CC capped RNAs (m7GpppG-capped RNA) but is required to stabilize the
CC movement of the N-terminal loop of NCBP2/CBP20 and lock the CBC into a
CC high affinity cap-binding state with the cap structure. Associates with
CC NCBP3 to form an alternative cap-binding complex (CBC) which plays a
CC key role in mRNA export and is particularly important in cellular
CC stress situations such as virus infections. The conventional CBC with
CC NCBP2 binds both small nuclear RNA (snRNA) and messenger (mRNA) and is
CC involved in their export from the nucleus whereas the alternative CBC
CC with NCBP3 does not bind snRNA and associates only with mRNA thereby
CC playing a role only in mRNA export. NCBP1/CBP80 is required for cell
CC growth and viability (By similarity). {ECO:0000250|UniProtKB:Q09161,
CC ECO:0000269|PubMed:19632182}.
CC -!- SUBUNIT: Component of the nuclear cap-binding complex (CBC), a
CC heterodimer composed of NCBP1/CBP80 and NCBP2/CBP20 that interacts with
CC m7GpppG-capped RNA. Found in a U snRNA export complex containing
CC PHAX/RNUXA, NCBP1/CBP80, NCBP2/CBP20, RAN, XPO1 and m7G-capped RNA.
CC Identified in a IGF2BP1-dependent mRNP granule complex containing
CC untranslated mRNAs. Interacts with PHAX/RNUXA, SRRT/ARS2, EIF4G2,
CC IGF2BP1, HNRNPF, HNRNPH1, KIAA0427/CTIF, PARN, DROSHA, UPF1 and
CC ALYREF/THOC4. May interact with EIF4G1; the interaction is however
CC controversial. The large PER complex involved in the repression of
CC transcriptional termination is composed of at least PER2, CDK9, DDX5,
CC DHX9, NCBP1/CBP80 and POLR2A (active). Component of an alternative
CC nuclear cap-binding complex (CBC) composed of NCBP1/CBP80 and NCBP3 (By
CC similarity). Interacts with METTL3 (By similarity). Interacts with
CC ZFC3H1 in a RNase-insensitive manner (By similarity). Interacts with
CC MTREX (By similarity). Interacts with TASOR (PubMed:31112734).
CC Interacts with DHX34; the interaction is RNA-dependent (By similarity).
CC Interacts with KPNA3 (By similarity). {ECO:0000250|UniProtKB:Q09161,
