Hypothesis
We hypothesized that AT-hook proteins were likely to be encoded within the Leishmania genome.
Conclusion
Our results indicate that AT-hook proteins are critical for the normal biology of Leishmania and may serve as therapeutic targets.
Supporting Evidence
- Several Leishmania ORFs predicted to be AT-hook proteins were identified using in silico approaches.
- LmjF06.0720 is nuclear in Leishmania, and this localization is disrupted upon exposure to drugs that displace AT-hook proteins.
- A novel peptido-mimetic agent derived from the sequence of LmjF06.0720 blocks the proliferation of Leishmania promastigotes.
Takeaway
Scientists studied a protein in Leishmania that helps the parasite grow and divide, which could be a target for new medicines.
Methodology
Biochemical, molecular, and cellular techniques were used to characterize the L. amazonensis ortholog of the L. major protein LmjF06.0720.
Limitations
The absence of antibodies against intact LamAT-Y limited the ability to dissect the function of this protein in Leishmania.
