Maistas

Maistas analyzes and structurally models alternative splicing isoforms derived from human genes to assess their potential functional plausibility.

Key Features:

• Isoform retrieval: Retrieves and analyzes all annotated isoforms associated with a specified gene or protein.
• Homology modeling: Generates three-dimensional models for selected isoforms using homology modeling techniques.
• Automatic plausibility assessment: Automatically assesses the plausibility of generated structural models to evaluate concordance with known functional structures.
• Structural deviation detection: Identifies significant structural deviations between isoforms that may indicate different functions or non-functional products.
• Functional implication analysis: Links homology-derived structural models to the interpretation of potential functional consequences of genetic variations.
• Focus on transcript diversity: Targets alternative splicing isoforms from human genes and considers the complexity of transcript diversity relative to annotated protein-coding genes.

Scientific Applications:

• Variant interpretation: Evaluating whether genetic variations affect isoform structures and their potential functionality.
• Alternative splicing research: Studying structural consequences of alternative splicing across isoforms of a gene.
• Isoform functionality assessment: Distinguishing likely functional protein isoforms from non-functional transcripts based on structural plausibility.
• Comparative isoform analysis: Comparing isoform structures to identify isoforms with markedly different folds or domain architectures.

Methodology:

Maistas retrieves annotated isoforms, generates homology-based three-dimensional models, and automatically assesses model plausibility and concordance with known functional structures.
