Leish-ExP

Leish-ExP catalogs protein sequences exclusive to five Leishmania species to support identification and characterization of parasite-specific drug targets.

Key Features:

• Species-Specific Protein Sequences: Contains protein sequences exclusive to five Leishmania species derived from whole-genome sequence data.
• Comparative Genomic Analysis: Identifies Leishmania-specific proteins through exhaustive comparative genomic analyses that distinguish parasite proteins from those of higher eukaryotes such as humans.
• Characterization of Uncharacterized Proteins: Provides sequence data, structural predictions, localization information, and potential functional insights for previously uncharacterized Leishmania proteins.
• Support for Targeted Drug Development: Curates Leishmania-specific proteins as candidate therapeutic targets to minimize off-target effects on human cells.

Scientific Applications:

• Target Identification: Enables selection of parasite-specific proteins as candidate drug targets.
• Functional Genomics Studies: Supports investigation of roles of uncharacterized proteins in Leishmania biology using sequence and predicted structural/localization data.
• Comparative Studies: Facilitates inter-species comparison of protein repertoires across Leishmania species to study species-specific adaptations and pathogenic mechanisms.

Methodology:

Exhaustive comparative genomic analyses of whole-genome sequence data were used to identify proteins exclusive to Leishmania by comparison with higher eukaryotes (e.g., human), followed by sequence-based characterization, structural prediction, localization inference, and annotation of identified proteins.
