NetAspGene

NetAspGene predicts splice sites in Aspergillus genomic sequences to enable accurate gene annotation and comparative analyses across Aspergillus species.

Key Features:

• Splice site prediction: Predicts donor and acceptor splice sites in genomic sequences of the genus Aspergillus.
• Training data: Developed and trained using gene sequences from Aspergillus fumigatus.
• Adaptation to Aspergillus intron architecture: Accounts for smaller intron sizes typical of Aspergillus genomes.
• Network architecture and windowing: Employs single local networks with a larger window size during training to capture donor and acceptor splice site information.
• Cross-species application: Applied to multiple species including Aspergillus nidulans, Aspergillus oryzae, and Aspergillus niger.
• Performance evaluation: Validated on independent datasets and reported to outperform other available splice site prediction tools.
• Splicing insights: Provides information relevant to both canonical and alternative splicing events.

Scientific Applications:

• Gene annotation: Improves quality and consistency of protein-coding gene annotations in Aspergillus genomes.
• Comparative genomics: Enables meaningful comparisons of gene structure across Aspergillus species.
• Splicing mechanism studies: Facilitates investigation of canonical and alternative splicing and their roles in gene regulation and expression.
• Fungal biology and pathogenesis research: Supports studies in fungal genomics, molecular biology, and aspects of pathogenesis.

Methodology:

Trained on Aspergillus fumigatus gene sequences using single local networks with an enlarged window size during training to capture donor and acceptor splice site signals; performance assessed on independent datasets.
