Robustness of signal transduction pathways

Area of Science:

• Cellular Biology
• Systems Biology
• Biochemistry

Background:

• Signal transduction pathways are critical for cell communication, mediating the transfer of external information to the nucleus.
• These pathways regulate fundamental cellular processes, including gene expression and cell fate determination.
• Information transfer within cells must be reliable and resistant to perturbations inherent in the cellular environment.

Purpose of the Study:
