Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to form...
Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

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 DNA...

Insertion of Multi-pass Transmembrane Proteins in the RER01:29

Insertion of Multi-pass Transmembrane Proteins in the RER

The rough ER membrane synthesizes, assembles, and embeds transmembrane proteins in diverse topologies. These proteins function as transporters or channels and can remain in the ER membrane or are sent to the Golgi complex, lysosome, and cell membrane.
The multipass transmembrane proteins are the type IV integral membrane proteins with multiple topogenic sequences determining their spatial arrangement in the ER membrane. Nearly all multipass proteins lack a cleavable signal sequence and use...
Peptide Identification Using Tandem Mass Spectrometry01:33

Peptide Identification Using Tandem Mass Spectrometry

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...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Understanding biological molecules requires identifying functional regions within their sequences.
  • Existing methods may not fully capture complex conserved and interdependent patterns.

Purpose of the Study:

  • To develop a novel method for segmenting biological sequences into functional regions.
  • To introduce and evaluate 'multipattern consensus regions' for enhanced sequence analysis.

Main Methods:

  • Utilizing multiple sequence alignments to identify statistical variation patterns.
  • Defining segmented regions based on conserved and interdependent patterns.
  • Applying the method to analyze the p53 cancer suppressor gene.

Main Results:

  • The proposed consensus regions effectively segment sequences based on statistically significant patterns.
  • Detected regions in p53 show significant links to mutation tendencies.
  • Associations were found between regions, 3D protein structure location, and hereditary cancer factors.

Conclusions:

  • Multipattern consensus regions offer a robust approach for functional region identification in biological sequences.
  • This method enhances understanding of protein function, mutation impact, and genetic predisposition to cancer.
