aquaporin
(= AQP; CHIP28)
Integral membrane protein (28 kD) with six trans-membrane domains that greatly increases water permeability. Found esp. in kidney, red blood cells. AQP1 forms a homotetramer of four independent channels. Arabidopsis has at least 20 distinct AQP genes. Members of the major intrinsic protein family.
