Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California The autonomic nervous system (ANS) controls the activity of the body's internal organs and regulates changes in their activity depending on the current environment. The vagus nerve, which innervates many of the internal organs, is an important part of the system. When our brain senses danger, vagal tone is inhibited, leading to a set of changes in the body designed to make us more prepared to fight or...

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Classification of Elements and Compounds

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units. Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...

RNA-Protein Pull-Down Assay to Isolate RNA-Binding Proteins via Affinity Extraction
0 Views •
2025
This video demonstrates an in vitro RNA pull-down assay to identify RNA-binding proteins (RBPs), which interact with the adenylate-uridylate-rich element (ARE) sequences in mRNA. The target RBPs from a cell lysate are mixed with an RNA probe to form RNA-protein complexes. The complexes are isolated via affinity purification utilizing the affinity of the desthiobiotin label of the RNA probe to a streptavidin-labeled magnetic bead.
FAQs
Specificity arises from the combined chemical and structural features of the RNA. Its nucleotide sequence contributes recognizable interaction patterns, while folding creates a three-dimensional surface that can be selectively contacted by an RNA-binding protein or another molecular partner. Because both features influence recognition, analyzing sequence alone may not fully explain how a regulatory interaction occurs.
Folding positions nucleotides into a particular three-dimensional conformation, creating structural features that a partner can recognize even when sequence information alone is insufficient. This makes RNA shape an important part of molecular selectivity. Differences in conformation can therefore influence which partner binds and how the resulting interaction affects RNA behavior inside the cell.
Binding can influence several stages of RNA fate and function, including processing, transport, stability, translation, and localization. The outcome depends on the molecular partner and the recognized RNA features. Through these interactions, cells connect a specific RNA site with downstream control of gene expression, extending regulation beyond the initial production of the RNA transcript.
They provide defined sites at which selective molecular recognition can be examined. Investigators can relate the element’s nucleotide sequence and folded structure to the behavior of its binding partner, then connect that interaction with changes in RNA regulation. This framework helps clarify how molecular contacts contribute to post-transcriptional control of gene expression in biology.
Characterization can identify the sequence or folded structural features associated with partner recognition and clarify how those features relate to RNA fate. It can also connect a binding event with effects on processing, transport, stability, translation, or localization. These findings help explain the regulatory behavior of an RNA rather than treating its sequence as an isolated information source.
Viral replication can be investigated through the RNA features that selectively interact with proteins or other molecular partners. Studying these elements helps researchers examine how RNA-protein recognition may relate to viral RNA function and replication. This application extends the topic beyond cellular gene regulation and uses molecular recognition as a way to analyze viral biology.
Their selective recognition properties make RNA recognition elements useful targets for molecular diagnostics and for designing RNA-based research tools. A diagnostic or experimental design can focus on a sequence or structural feature that a partner recognizes, linking molecular specificity to detection or controlled investigation of RNA activity. The same principle also supports therapeutic regulation of RNA function.
