Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables ephrin receptor binding activity; potassium ion transmembrane transporter activity; and water transmembrane transporter activity. Involved in several processes, including defense response to Gram-negative bacterium; lateral ventricle development; and metanephros development. Acts upstream of or within several processes, including corticotropin secretion; glomerular filtration; and renal water absorption. Located in several cellular components, including basolateral plasma membrane; brush border; and extracellular exosome. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; sensory organ; and skeleton. Orthologous to human AQP1 (aquaporin 1 (Colton blood group)).
