Aquaporin-1

Meaning

Aquaporin-1, often abbreviated as AQP1, is a specialized integral membrane protein that functions as a highly efficient, water-selective channel across cell membranes. This protein is a member of the larger aquaporin family, which facilitates the rapid, passive movement of water molecules down osmotic gradients. Its presence is fundamentally essential for managing the body’s water balance and maintaining the critical volume and concentration of circulating fluids. Understanding its function is key to appreciating the intricacies of renal and circulatory physiology.
