Lipid Raft Function

Meaning

Lipid Raft Function refers to the specialized, highly ordered microdomains within the cellular plasma membrane, which are enriched in cholesterol, sphingolipids, and specific proteins, acting as crucial organizing centers for cellular signaling. These dynamic structures concentrate receptors and signaling molecules, facilitating rapid and efficient signal transduction pathways in response to external stimuli, including hormones and growth factors. The integrity of lipid raft function is paramount for robust cell-to-cell communication and hormonal responsiveness.
