Data show that Cbp80 knockdown not only led to the upregulation of transposons, but also to delocalization of Piwi (show PIWIL1 Proteins), Aub and Ago3 (show EIF2C3 Proteins), key factors in the piRNA biosynthesis pathway.
Sgf11 interacts with the cap-binding protein 80 (Cbp80) component of the cap-binding complex, and that Cbp80 knockdown interferes with Sgf11 recruitment on the hsp70 promoter.
Study proposes the existence of an alternative cap-binding complex involving NCBP1 and NCBP3 that plays a key role in mRNA biogenesis.
down-regulation of CTIF (show KIAA0427 Proteins) using a small interfering RNA causes a redistribution of CBP80 from polysome fractions to subpolysome fractions, without significant consequence to eIF4E (show EIF4E Proteins) distribution
Cellular processes by which CBP80-CBP20 (show NCBP2 Proteins) -bound messenger ribonucleoproteins (mRNPs) are remodeled to eIF4E (show EIF4E Proteins)-bound mRNPs, are overviewed.
Viral mRNA associates with the influenza virus A NS1 (show PTPN11 Proteins) and the cellular NCBP1 of the nuclear cap-binding complex.
UPF1 (show UPF1 Proteins) binds PTC (show F9 Proteins)-containing mRNA more efficiently than the corresponding PTC (show F9 Proteins)-free mRNA in a way that is promoted by the UPF1 (show UPF1 Proteins)-CBP80 interaction.
crystal structure at 2.1 A resolution of CBP20 (show NCBP2 Proteins) and CBP80 bound to an m(7)GpppG cap analogue
Structural basis of m7GpppG binding to the nuclear cap-binding protein (show EIF4E Proteins) complex.
The organization of the CBP80-CBP20 (show NCBP2 Proteins) complex suggests how the activity of eIF4G (show EIF4G1 Proteins) in translation initiation could be regulated through a dynamic network of overlapping intra- and intermolecular interactions.
During nonsense-mediated mRNA decay, CBP80 interacts with Upf1 (show UPF1 Proteins) and promotes the interaction of Upf1 (show UPF1 Proteins) with Upf2 but not with Stau1 (show STAU1 Proteins).
Association of CBC with PARN (show PARN Proteins) might have importance in the regulated recruitment of PARN (show PARN Proteins) to the nonsense-mediated decay pathway during the pioneer round of translation.
the identification of new genes involved in ABA-dependent abiotic stresses using Arabidopsis suppressor mutants of abh1 (show ALKBH Proteins) hypersensitivity to ABA during seed germination.
Data suggest that CBP20 (show NCBP2 Proteins) and CBP80 (ABH1) have synergistic roles during the salt stress response.
SERRATE, CAP BINDING PROTEIN20 (CBP20 (show NCBP2 Proteins)), and CBP80 are regulators of lincRNA expression and biogenesis. RT-PCR experiments confirmed these three proteins are also needed for splicing of a small group of intron-containing lincRNAs.
This intron suppression of transgene silencing requires efficient intron splicing and is dependent on ABH1 (show ALKBH Proteins).
ABH1 (CBP80) encodes a large subunit of CBC (CAP BINDING COMPLEX) and the abh1 (show ALKBH Proteins) mutant is drought-tolerant and hypersensitive to ABA during seed germination.
The cbp80(abh1) and cbp20 (show NCBP2 Proteins)/80 mutants had many more changes in alternative splicing in common than did cbp20 (show NCBP2 Proteins) and cbp20 (show NCBP2 Proteins)/80 suggesting that CBP80 plays a more significant role in alternative splicing than CBP20 (show NCBP2 Proteins).
Abh1 (show ALKBH Proteins) lesion affects several developmental processes, perhaps because the processing of certain mRNAs.
CBP20 and CBP80 function in miRNA biogenesis by binding to pri-miRNA transcripts, and are stabilized by ABA by a post-translational mechanism.
AtCBP80 is required for the stability of AtCBP20 (show NCBP2 Proteins) in the plant cell.
The product of this gene is a component of the nuclear cap-binding protein complex (CBC), which binds to the monomethylated 5' cap of nascent pre-mRNA in the nucleoplasm. The encoded protein promotes high-affinity mRNA-cap binding and associates with the CTD of RNA polymerase II. The CBC promotes pre-mRNA splicing, 3'-end processing, RNA nuclear export, and nonsense-mediated mRNA decay.
