TelFinder
TelFinder identifies telomeric motif sequences de novo from genomic datasets to detect tandem repeats at chromosome ends and support studies of telomere composition and evolution.
Key Features:
- De novo detection: Identifies telomeric motif sequences without prior knowledge of species-specific telomeric repeats.
- Tandem repeat identification: Detects tandemly repeated sequences characteristic of telomeres at chromosome ends.
- Cross-species detection: Applies to genomic datasets from diverse species to discover previously uncharacterized telomeric motifs.
- Variation analysis: Performs variation analyses of telomere motif sequences across chromosomes and chromosome ends.
- Validation against Telomerase Database: Achieved a 90% detection rate when tested against known telomeric sequences from the Telomerase Database.
- Complex motif detection: Capable of identifying complex telomeric motifs within genomic data.
Scientific Applications:
- Telomere composition and evolution: Enables analysis of telomere sequence composition and investigation of divergent telomeric evolution.
- Aging and senescence studies: Supports research into cellular senescence and telomere-associated mechanisms of aging.
- Cancer research: Facilitates examination of telomere dynamics relevant to cancer and chromosome stability.
- Comparative genomics: Supports comparative analysis of telomeric motifs across multiple chromosomes and species.
Methodology:
Analyzes genomic datasets to identify telomeric motifs de novo; performs variation analyses of telomere sequences across chromosomes and chromosome ends; validated by testing against known telomeric sequences from the Telomerase Database with a reported 90% detection rate.
