Peptide Identification Using Tandem Mass Spectrometry01:33

Peptide Identification Using Tandem Mass Spectrometry

7.1K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

Multi-species Conserved Sequences

4.3K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Area of Science:

  • Genomics
  • Proteomics
  • Bioinformatics

Background:

  • The human genome's complexity is underestimated.
  • Short open reading frames (sORFs) are increasingly identified.
  • sORFs encode small proteins called micropeptides.

Purpose of the Study:

  • To review human micropeptides encoded by various transcripts.
  • To highlight the significance of sORFs in genome annotation.

Main Methods:

  • Advanced analytic techniques like ribosome profiling and mass spectrometry.
  • Improved bioinformatics technology for genome annotation.

Main Results:

  • Thousands of likely coding sORFs identified in the human genome.
  • sORFs are encoded by diverse transcripts, including mitochondrial rRNAs, lncRNAs, circRNAs, and upstream of mRNAs.
  • sORF products contribute to genomic complexity.

Conclusions:

  • The discovery of micropeptides expands our understanding of the human genome.
  • sORFs represent a significant area for future research in genetics and molecular biology.
