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,...

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...

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Prediction Intervals

Prediction Intervals

The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Background:

Protein gamma-turns are crucial for protein function and experimental design.
Existing gamma-turn prediction methods yield unsatisfactory results, with Matthew correlation coefficients (MCC) typically between 0.2-0.4.

Purpose of the Study:

To develop a more accurate method for protein gamma-turn prediction.
To explore the utility of deep neural networks, specifically Capsule Networks (CapsuleNet), for this task.

Main Methods:

Proposed a deep inception capsule network (CapsuleNet) for gamma-turn prediction.
Utilized CapsuleNet's ability to extract high-level features from limited input data.

Main Results:

Achieved an MCC of 0.45 on the GT320 benchmark dataset, surpassing the previous best MCC of 0.38.
Demonstrated superior performance compared to existing gamma-turn prediction methods.

Conclusions:

The proposed deep inception capsule network significantly improves gamma-turn prediction accuracy.
This work represents the first application of deep neural networks and capsule networks in bioinformatics for gamma-turn prediction, providing a valuable model for future research.
