Summary
Mass spectrometry-based proteomics is key to understanding non-coding RNA (ncRNA) interactions and functions. This approach identifies protein partners and quantifies ncRNA effects on gene expression, particularly for microRNA (miRNA) targets.
Area of Science:
- Molecular Biology
- Biochemistry
- Genomics
Background:
- Non-coding RNAs (ncRNAs) play vital roles in gene expression regulation within ribonucleoprotein (RNP) complexes.
- The precise biological functions and interaction mechanisms of most ncRNAs remain largely uncharacterized.
- Understanding ncRNA-protein interactions is essential for elucidating ncRNA stability, localization, and function.
Purpose of the Study:
- To provide an overview of Mass Spectrometry (MS)-based proteomics for studying ncRNA-protein interactions.
- To summarize methods for identifying ncRNA interactors and characterizing RNP complex composition.
- To highlight proteomics strategies for analyzing ncRNA-mediated gene expression changes, focusing on microRNA (miRNA) targets.
Main Methods:
- Overview of fundamental principles of MS-based proteomics for protein identification and quantification.
- Recapitulation of approaches for screening ncRNA-binding proteins.
- Description of strategies for dissecting ncRNA-protein complex composition.
- Presentation of proteomics methods to characterize ncRNA effects on global protein levels.
Main Results:
- Mass Spectrometry (MS) is a powerful tool for identifying proteins interacting with specific ncRNAs.
- MS enables the quantification of protein level changes influenced by ncRNAs.
- Proteomics strategies facilitate the systematic identification of microRNA (miRNA) targets and their associated proteins.
Conclusions:
- MS-based proteomics is instrumental in exploring the ncRNA landscape and its regulatory roles.
- This technology aids in understanding the composition and function of ncRNA-protein complexes.
- Proteomics provides a systematic approach to unraveling the impact of ncRNAs on gene expression and identifying key regulatory interactions.

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:19Mass Spectrometry: Overview
8.9K
Mass spectrometry is an analytical technique used to determine the molecular mass and molecular formula of a compound. The basic principle of mass spectrometry is to generate ions from the analyte molecule and measure these ion abundances against their molecular mass. One common type of ionization, known as electron ionization or EI, bombards the analyte molecules in the gas phase with high-energy electron beams. The electron beams displace an electron from the molecule and leave behind a...

2.5K
Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...

5.4K
In mass spectroscopy, amines undergo fragmentation to give parent ions with odd molecule weights. This observed mass spectrum follows the nitrogen rule; a molecule with an odd number of nitrogen atoms produces a molecular ion with an odd molecular weight. Amines undergo fragmentation through α cleavage, producing nitrogen-containing cations—iminium ions—and alkyl radicals. Mass spectra of aromatic and cyclic aliphatic amines exhibit strong molecular ion peaks, but acyclic...

01:13Mass Spectrometry: Isotope Effect
4.3K
Most elements exist in nature as a mixture of isotopes. The isotopes differ in weight due to their respective number of neutrons. The molecular weight of a molecule is different depending on the specific isotope of its elements involved. As a result, the mass spectrum of the molecule exhibits peaks from the same fragment at multiple positions. The positions of these mass signals depend on the mass differences between isotopes. Furthermore, the intensity of these signals is dependent on the...

1.5K
The molecular ion peak of a molecule in the mass spectrum provides vital information for molecular identification. However, conventional electron impact ionization can lead to the rapid dissociation of some molecular ions before they reach the detector. A milder ionization method is required to increase the lifetime of such ionized analyte molecules. Chemical ionization (CI) is a gas-phase protonation reaction useful for mass-analyzing analyte molecules that are easily protonated to yield the...
