Cis-regulatory Sequences

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Protein and Protein Structure

Protein and Protein Structure

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Per-Unit Sequence Models

Per-Unit Sequence Models

An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Improving Translational Accuracy

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Background:

Non-coding RNA (ncRNA) and protein interactions are crucial for cellular processes like gene expression.
Existing experimental methods for predicting these interactions are costly and resource-intensive.

Purpose of the Study:

To develop an innovative, accurate, and practical computational method for predicting ncRNA-protein interactions.
To address the limitations of current experimental prediction techniques.

Main Methods:

A deep learning method, BGFE, was developed using protein sequences represented by bi-gram probability features from Position Specific Scoring Matrix (PSSM).
ncRNA sequences were represented using k-mers sparse matrices.
A stacked auto-encoder network with a stacked ensemble integration strategy was employed for high-level feature extraction.

Main Results:

The BGFE method demonstrated high prediction accuracy and effectiveness across three independent datasets.
Performance was validated using a five-fold cross-validation and feature classification via a random forest classifier.

Conclusions:

The proposed BGFE method is a powerful and accurate tool for predicting ncRNA-protein interactions.
This approach offers valuable guidance for future research in ncRNA-protein interaction studies.
