Human nuclear cap-binding protein complex shows the large subunit, CBC80 consists of 757 amino acid residues.
2.
When RNA is exported to the cytoplasm the nuclear cap-binding protein complex is replaced by cytoplasmic cap binding complex.
3.
The nuclear cap-binding complex is a functional heterodimer and composed of Cbc1 / Cbc2 in yeast and CBC20 / CBC80 in multicellular eukaryotes.
4.
"' Nuclear cap-binding protein complex "'is a RNA-binding protein which binds to the 5'cap of pre-mRNA . The cap and nuclear cap-binding protein have many function in mRNA biogenesis including splicing, 3'- end formation by stabilizing the interaction of the 3'- end processing machinery, nuclear export and protection of the transcripts from nuclease degradation.
