Phosphoinositide signaling

Phosphoinositide signaling is a process by which cells transmit signals using specific lipid molecules in their membranes. When a cell receives a signal, enzymes modify phosphoinositides—special lipids—by adding or removing phosphate groups. These modifications act as biological switches, attracting or releasing proteins that control cellular activities like growth, movement, or division. This signaling pathway is essential for proper cell function and communication, playing a critical role in processes such as immune responses, development, and maintaining cell health.
