Native polyacrylamide gel electrophoresis is a fundamental tool for analyzing RNA-protein interactions. Traditionally most experiments have used vertical gels. However, horizontal gels provide several advantages, such as the opportunity to monitor complexes during electrophoresis. We provide a detailed protocol for generating and using horizontal native gel electrophoresis.

Here, we present a protocol to enrich endogenous RNA binding sites or "footprints" of RNA:protein (RNP) complexes from mammalian cells. This approach involves two immunoprecipitations of RNP subunits and is therefore dubbed RNA immunoprecipitation in tandem (RIPiT).

Here, we describe the assembly of RNA polymerase II (Pol II) elongation complexes requiring only short synthetic DNA and RNA oligonucleotides and purified Pol II. These complexes are useful for studying mechanisms underlying co-transcriptional processing of transcripts associated with the Pol II elongation complex.

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated. This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...

RNA Splicing

Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...
FAQs
N proteins do not associate with RNA in a purely nonspecific manner. Their binding can depend on features in the RNA sequence or structure, which influences where association occurs along the strand. These interactions help organize the genome into a compact nucleocapsid and may determine how effectively the resulting assembly supports later replication or transcription processes.
The assembled nucleocapsid can provide an organized RNA template for viral replication and transcription. By associating the genome with N proteins, the complex connects RNA organization with the processes that produce copied genetic material or RNA transcripts. Studying this relationship helps explain how genome packaging is linked to functional stages of the viral life cycle.
Genome encapsidation and particle formation are connected through the ability of N proteins to assemble along viral RNA. This organization helps package the genetic material into a compact form while contributing to the structure of the viral particle. Examining these linked events can reveal how RNA organization influences the formation of infectious viral assemblies.
Structural and biochemical analysis can clarify how N proteins associate with RNA, how assemblies become compact, and how those properties relate to replication, transcription, packaging, and particle formation. The resulting information provides a basis for investigating viral genome organization and for identifying features of the complex that may be useful in diagnostics or antiviral research.
Because genome encapsidation depends on N-protein and RNA interactions, disrupting those interactions is a potential antiviral strategy described by this research context. Studies can focus on structural or biochemical features required for assembly and packaging. Understanding which properties support a functional complex may help identify targets for interfering with viral genome organization and replication.
Their distinctive structural and biochemical properties make N-RNA complexes relevant to investigations of viral material and genome organization. In biology research, they connect molecular RNA binding with larger outcomes such as packaging, particle formation, replication, and transcription. These relationships can inform diagnostic research while also improving understanding of how RNA viruses organize their genetic material.
