Function

function

Water channel required to facilitate the transport of water across membranes (PubMed:23157494).
Stimulates plant drought tolerance by facilitating the transport of water from the arbuscular mycorrhiza fungus to host plants (PubMed:23157494).

Catalytic activity

Activity regulation

Polyethylene glycol (PEG) stimulates whereas glycerol inhibits the aquaporin activity.
