Water channel protein facilitating water transport through membranes.
Membrane protein forming selective channels allowing rapid and efficient passage of water molecules through cell membranes.
Aquaporins are protein channels that allow rapid water movement in response to osmotic gradients, bypassing the impermeable lipid bilayer. There are at least 13 isoforms in humans, expressed in different tissues according to hydration needs. Aquaporins can also transport small molecules such as glycerol and urea. Their activity is regulated by phosphorylation and membrane translocation. Aquaporin dysfunction is involved in certain pathologies such as nephrogenic diabetes insipidus.
Facilitates rapid and regulated water transport through cell membranes.
Understand that water transport efficiency depends on these protein structures. Maintain adequate electrolyte balance to optimize aquaporin function.
Aquaporins are essential molecular structures for effective cellular water transport.
