Ribosome Profiling02:24

Ribosome Profiling

4.3K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Western Blotting01:15

Western Blotting

22.1K
Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

15.0K
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...

    Area of Science:

    • Genomic sequence analysis
    • Bioinformatics
    • Computational biology

    Background:

    • Predicting protein-coding regions is crucial for understanding genomic function.
    • Existing spectrum-based methods often rely on fixed, experimentally determined window lengths, limiting their adaptability.
    • This limitation can impact the accuracy of protein-coding region prediction, especially for sequences with varying characteristics.

    Purpose of the Study:

    • To introduce a novel Wide-Range Wavelet Window (WRWW) method for enhanced protein-coding region prediction.
    • To address the limitations of fixed window length dependencies in traditional spectrum-based approaches.
    • To evaluate the performance of the WRWW method across diverse genomic datasets.

    Main Methods:

    • Development of the Wide-Range Wavelet Window (WRWW) technique.
    • Analysis of the WRWW's adaptive frequency response and window width accommodation.
    • Comparative experimental analysis using five benchmark datasets against established spectrum-based methods.

    Main Results:

    • The WRWW method demonstrates superior performance in predicting protein-coding regions compared to existing spectrum-based techniques.
    • The adaptive nature of the WRWW allows for effective analysis across a wide range of window lengths without performance degradation.
    • The WRWW method shows dominance in accurately identifying both short and long exons.

    Conclusions:

    • The WRWW method offers a significant advancement in the prediction of protein-coding regions within genomic sequence analysis.
    • Its adaptive windowing capability overcomes key limitations of previous methods, leading to improved accuracy.
    • The WRWW is particularly effective for identifying diverse exon types, enhancing its utility in bioinformatics research.
