Modification of 5’Cap For The Improvement Of Stability Of mRNA

Our vast expertise in safely manufacturing 5’ cap for many biological study types. We are offering partners full tools that enable them to locate, create, and market immunotherapy from concept to market, all for the benefit of clients globally.

On the 5′ ends of various primary transcripts, including precursor messenger RNA is a nucleotide that has undergone a particular alteration known as the five-prime cap (5′ caps). This tightly controlled process, known as mRNA capping, is essential for producing mature, stable messenger RNA that can be translated during protein synthesis. Chloroplast and mitochondrial mRNA do not have caps.

In eukaryotes, the uncommon 5′ to 5′ triphosphate bond between a guanine nucleotide and an mRNA molecule forms the 5′ cap, which is present on the 5′ ends of an mRNA molecule. In the presence of a methyltransferase, this guanosine is immediately methylated on the 7 positions after capping. 

Capping process

◆ The 5′ end of an RNA molecule that is left unchanged and ends in a triphosphate group serves as the beginning point for capping with 7-methylguanylate.

◆ The 5′ carbon is joined to three phosphate groups before the last nucleotide. Before transcription is finished, the capping step begins when the immature pre-mRNA is created.

◆ RNA triphosphatase eliminates one of the terminal phosphate groups, leaving a bisphosphate group.

◆ The mRNA guanylyltransferase removes pyrophosphate from the GTP substrate before adding GTP to the terminal bisphosphate. 

◆ The 5′-5′ triphosphate connection is created as a consequence, yielding 5.

◆ mRNA (guanine-N7-)-methyltransferase methylates the 7-nitrogen of guanine, and S-adenosyl-L-methionine is demethylated to form S-adenosyl-L-homocysteine, culminating in 5′. 

◆ The cap-adjacent modifications that commonly affect the first and second nucleotides can produce up to 5′. 

◆ If 2′-O-ribose methyl-adenosine is the closest cap-adjacent nucleotide, it can be further methylated at the N6 methyl site to create N6-methyladenosine, which results in 5′.

Functions

◆ Controlling nuclear export

◆ Preventing exonuclease degradation; 

◆ Encouraging translation

◆ Support for the removal of the 5' proximal intron

What Can We Do?

• ARCAs Cap

A type of cap analog called anti-reverse cap analog (ARCA) is utilized in the in vitro transcription process to create capping transcripts. ARCA is capped to guarantee excellent translation efficiency.

• Flashing Cap

In the study of capping/decapping reactions, translation, and other biophysical research, fluorescent cap mRNA molecules are frequently utilized. Fluorescent labeling is also highly useful for monitoring RNA molecules in cells.

• Cap that Contains Fluorophosphates

To track the activity of enzymes with varying specificities and metal ion needs, fluorophosphates nucleotide analogs can be utilized. Additionally, these substances can be utilized as reporting ligands for research on protein binding.

• Cap containing 6-thioguanine

Modifications to RNA caps enable mild cross-linking with interacting proteins or nucleic acids as well as altering the stability and effectiveness of mRNA translation. One of these is a synthetic cap analog mRNA with in vitro transcriptional incorporation of 6-thioguanine (IVT).
