GONUTS is under stress! The website is currently experiencing long-wait times and frequent time-outs due to the record number of students, groups, and annotations related to CACAO this semester. We are currently working on increasing performance -- please accept our apologies for the technical difficulties.
You can help reduce stress on the server by:
- not reloading pages frequently - this just adds
- opening links in new windows (so you can read the old page)
Category:GO:0005846 ! nuclear cap binding complex
name: nuclear cap binding complex
namespace: cellular_component
def: "A conserved heterodimeric protein complex that binds to the 5' terminal cap structure m7G(5')ppp(5')N of nascent eukaryotic RNA polymerase II transcripts such as pre-mRNA and U snRNA. The consists of proteins known as CBP20 and CBP80, binds to cap structures in the nucleus, and is involved in pre-mRNA splicing, 3'-end formation, and RNA nuclear export." [PMID:16043498]
comment: Note that this complex can be found in the cytoplasm as well as the nucleus.
