  5' cap - Wikipedia, the free encyclopedia
The 5' cap is a specially altered dinucleotide end to the 5' end of preliminary messenger RNA as found in eukaryotes.
Capping ensures the messenger RNA's stability while it undergoes translation in the process of protein synthesis, and is a highly regulated process which occurs in the nucleus.
As soon as the 5' end of the new transcript emerges the enzymes transfer to it and begin the capping process (this is a similar kind of mechanism to ensure capping as for polyadenylation).

 Messenger RNA - Wikipedia, the free encyclopedia
G cap, is a modified guanine nucleotide that has been added to the "front" or 5' end of the messenger RNA shortly after the start of transcription.
The 5' cap consists of a terminal 7-methylguanosine residue which is linked through a 5'-5'-triphosphate bond to the first transcribed nucleotide.
After the 5' end has been capped, it is released from the cap-synthesizing complex and is subsequently bound by a cap-binding complex associated with RNA polymerase.

 BIOL414/614 at UMBC - roles_of_the_5_prime_cap
Ultimately, studies suggest that the binding of CBC to the 5' cap facilitates an early stage in the assembly of the splicing complex, thereby, illustrating another vital function for 5' capping (Lewis et al 1996a).
Finally, eIF-4E is a translation initiation factor that recognizes the 5' cap on mRNA transcripts, binds to it, and triggers mRNA binding to ribosomes.
This direct connection between the 5' cap and translation initiation demonstrates the importance of the 5' cap in initiating the translation of mRNA transcripts into protein(Lejbkowicz et al 1992).

 SparkNotes: Post-Transcriptional RNA Processing: The 5' Cap and the Poly A Tail
At the end of transcription, the 5' end of the RNA transcript contains a free triphosphate group since it was the first incorporated nucleotide in the chain.
The cap is formed through a 5'-5' linkage between the two substrates such that the GTP molecule is oriented in the opposite direction as the other nucleotides in the RNA transcript chain.
Once in place, the cap plays a role in the ribosomal recognition of messenger RNA during translation into a protein.

 Discrimination between mono[ndash]and trimethylated cap structures by two isoforms of Caenorhabditis elegans eIF4E
G-containing caps by mRNAs through the process of trans-splicing, in which a 22 nucleotide spliced leader is transferred from the 5'-end of an snRNA to an acceptor site in the 5' end of the pre-mRNA (Blumenthal, 1998).
In all three cases, the changes in cap selectivity caused by substitutions in the 3−4 loop are attenuated by substitutions in the 1−2 loop, causing the proteins to behave more like wt IFE-5.
It is conceivable that the formation of this disulfide bond serves as a reversible switch that responds to the redox state of the cell, as has recently been reported for the molecular chaperone Hsp33 (Jakob et al., 1999).

 Nokia Calls for 5% Cap on 3G Patent Royalties
Finnish cell phone giant Nokia Corp. (Quote, Chart) on Wednesday urged competitors to place a hard cap on royalty rates for 3G patents, arguing that such a move would promote the spread of the WCDMA technology.
Under the Nokia proposal, which would be applicable to both network gear and phones, patent holders would agree to limit the cumulative royalty rate to a maximum of 5 percent, regardless of how many patents the equipment includes.
Royalty rates for the much-vaunted Wideband Code Division Multiple Access (WCDMA) technology are generally computed as a percentage of the price of the equipment using patents.
