Why in news
Researchers at IISc and IMSc discovered that the Lsr2 protein in the tuberculosis bacterium protects it from foreign DNA by forming condensates.
Background
The study identifies the Lsr2 protein's role in protecting the tuberculosis bacterium from foreign DNA. It functions by binding to large regions of DNA rich in adenine and thymine to form condensates that prevent the expression of harmful proteins.
Facts for Prelims
- S&TLsr2: A protein in the tuberculosis bacterium that protects it from foreign DNA.
- S&TMechanism: Lsr2 binds to DNA regions rich in adenine and thymine to form condensates.
- BodyIISc (Indian Institute of Science) and IMSc (Institute of Mathematical Sciences) conducted the collaborative study.
For Mains
Q. Discuss how advancements in molecular biology and protein research can contribute to the development of targeted therapies for multi-drug resistant tuberculosis in India.
