AluGene: a database of Alu elements incorporated within protein-coding genes

Area of Science:

• Genomics
• Molecular Biology
• Bioinformatics

Background:

• Alu elements are abundant short interspersed nuclear elements (SINEs) in the human genome.
• Despite their small size (~300 nucleotides), Alu elements influence gene structure, protein sequences, splicing, and expression patterns.
• Existing genomic data on Alu elements within protein-coding genes are fragmented across disparate databases.

Purpose of the Study:

• To create a centralized, comprehensive genomic database of Alu sequences within human protein-coding genes.
• To provide researchers with easy access to annotated Alu element data, facilitating evolutionary and functional studies.
• To address the limitations of scattered and incompatible data sources.

Main Methods:

• Development of the AluGene database (http://Alugene.tau.ac.il/).
• Annotation of Alu elements based on their location within coding regions and exon/intron boundaries.
• Integration of structural and positional information from various genomic sources.

Main Results:

• AluGene offers a complete Alu map of the human genome with associated information.
• The database annotates Alu elements concerning their location within coding regions and exon/intron structures.
• A unified search page allows querying Alu sequences, locations, motifs, and compositional properties.

Conclusions:

• AluGene serves as a valuable resource for studying the evolutionary impact of Alu elements.
• The database simplifies the investigation of Alu elements' roles in gene structure and function.
• This centralized resource facilitates research by consolidating dispersed genomic data.
