Catabolite Activator Protein (blue) bound to a piece of DNA (red). In cell biology, catabolite activator protein (CAP), which is also known as cAMP receptor protein (CRP), is a trans-acting transcriptional activator in bacteria that effectively catalyzes the initiation of DNA transcription by interacting with RNA polymerase in a way that causes the DNA to bend.
In 2013, Batut et al. [13] combined CAP trapper, template switching, and 5′-phosphate-dependent exonuclease digestion in RAMPAGE to maximize promoter specificity. In 2014, Murata et al. [ 14 ] published the nAnTi-CAGE protocol, where capped 5′ ends are sequenced on the Illumina platform with no PCR amplification and no tag cleavage.
Shortly after transcription is initiated in eukaryotes, a pre-mRNA's 5' end is modified by the addition of a 7-methylguanosine cap, also known as a 5' cap. [9] The 5' capping modification is initiated by the addition of a GTP to the 5' terminal nucleotide of the pre-mRNA in reverse orientation followed by the addition of methyl groups to the G ...

In molecular biology, the five-prime cap (5′ cap) is a specially altered nucleotide on the 5′ end of some primary transcripts such as precursor messenger RNA. This process, known as mRNA capping , is highly regulated and vital in the creation of stable and mature messenger RNA able to undergo translation during protein synthesis .
5' cap structure. A 5' cap (also termed an RNA cap, an RNA 7-methylguanosine cap, or an RNA m 7 G cap) is a modified guanine nucleotide that has been added to the "front" or 5' end of a eukaryotic messenger RNA shortly after the start of transcription. The 5' cap consists of a terminal 7-methylguanosine residue that is linked through a 5'-5 ...
The initiation of mRNA can proceed in a cap-independent manner, through recruiting 40S to IRES (Internal Ribosome Entry Site) located in 5'UTR region. The actual work of RNA silencing is performed by RISC in which the main catalytic subunit is one of the Argonaute proteins (AGO), and miRNA serves as a template for recognizing specific mRNA ...
