Aqp5 Gene Summary [Mouse]

Predicted to enable identical protein binding activity and water channel activity. Acts upstream of or within camera-type eye morphogenesis; saliva secretion; and water transport. Located in several cellular components, including apical plasma membrane; basal plasma membrane; and microvillus. Is expressed in several structures, including exocrine system; lung; nucleus pulposus; oocyte; and sensory organ. Used to study dry eye syndrome. Human ortholog(s) of this gene implicated in Bothnian type palmoplantar keratoderma. Orthologous to human AQP5 (aquaporin 5). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Aqp5 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
