How Do Cells Use Membrane Rafts for Cell Signaling?

💡 The Answer

  • Membrane rafts are cholesterol‑ and sphingolipid‑rich microdomains in the outer leaflet.
  • They concentrate signaling receptors like GPCRs and receptor tyrosine kinases.
  • Rafts facilitate efficient protein‑protein interactions and signal transduction cascades.
  • Pathogens such as HIV also hijack rafts to enter and exit host cells.
