phosphoinositides

Phosphoinositides are a group of specialized lipid molecules found in cell membranes that play crucial roles in signaling and cellular communication. They act as molecular markers, helping cells organize processes like growth, movement, and responses to environmental cues. By recruiting and activating specific proteins at the membrane, phosphoinositides help coordinate the activity of pathways essential for cell function. Their precise regulation is vital for maintaining cellular health, and abnormal phosphoinositide signaling is linked to diseases such as cancer and neurological disorders.
