Aquaglyceroporin that may modulate the water content and osmolytes during anhydrobiosis (PubMed:23761966). Most abundant aquaporin in early embryonic state, adult active, and adult anhydrobiotic state (PubMed:23761966, PubMed:23029181). Expression is slightly up-regulated in early embryonic state (PubMed:23029181). Aquaporins contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA). Belongs to the MIP/aquaporin (TC 1.A.8) family.
