How Do Lipid Rafts Function in Cell Signaling?

💡 The Answer

• Lipid rafts are microdomains enriched in cholesterol and sphingolipids that cluster specific proteins.
• They serve as platforms for signal transduction by concentrating receptors and signaling molecules.
• Rafts facilitate efficient activation of pathways like T-cell receptor signaling and growth factor responses.
• Their dynamic nature allows rapid assembly and disassembly to modulate cellular responses.
