Optogenetics and protein engineering applications in cancer research: a GS3 Science & Technology topic.
Why in news
Researchers at the Indian Institute of Science (IISc) developed the Light-Induced Spindle Activation (LISA) technique to reversibly activate Aurora A kinase for studying and potentially treating cell division defects.
Background
Prof. Sachin Kotak's team at IISc engineered human cells to express a fusion protein linking Aurora A to CRY2. The LISA technique uses blue light to cause protein clustering, enabling the study of spindle assembly and potential treatment of solid tumors.
Facts for Prelims
- S&TLISA: Light-Induced Spindle Activation technique developed by IISc
- S&TAurora A kinase: A protein crucial for spindle assembly during cell division
- S&TCRY2: A protein used in the LISA technique to facilitate clustering upon blue light exposure
- FactLISA technique allows for the reversible activation of Aurora A kinase
Prelims practice question
Which protein is used in the LISA technique to facilitate clustering upon exposure to blue light?
- (a)SOD1
- (b)GFP
- (c)CRY2
- (d)Aurora B
Show answer
Answer: (c) CRY2 — The note states that CRY2 is the protein used in the LISA technique to facilitate clustering upon blue light exposure.
