Symbol: aqp-1 Name: AQuaPorin or aquaglyceroporin related 1 Entrez gene ID: 174190 Ensembl gene ID: F32A5.5 Species: Worm (Taxid: 6239) Functional description: Protein AQP-1; AQuaPorin or aquaglyceroporin related family member (aqp-1) [Source:RefSeq peptide;Acc:NP_495510] [Ensembl]; aqp-1 encodes, by alternative splicing, two isoforms of an aquaglyceroporin required for normally short lifespan; AQP-1 expression is upregulated under daf-2(-) conditions, and loss of AQP-1 function in daf-2 mutant animals results in reduced lifespan; AQP-1 increases glycerol permeability five- to seven-fold when expressed in Xenopus oocytes; AQP-1::GFP fusion proteins are expressed predominantly in the intestine, where they localize to the basolateral plasma membrane, but are also expressed in the pharynx; intestinal expression of AQP-1 is repressed by infection with Pseudomonas aeruginosa. [WormBase] Observation: aqp-1 expression changes in response to glucose or glycerol. Similar to daf-16 and hsf-1 mutants, aqp-1 mutants were short-lived, and their short lifespan was not further decreased by glucose. Overexpression of aqp-1::GFP rescues short lifespan of aqp-1 deletion mutants and partially prevented glucose from shortening lifespan. Glucose or glycerol feeding downregulates aqp-1 in wild-type. In daf-16 and/or hsf-1 mutants aqp-1 is repressed and glucose feeding does not significantly affect its expression. aqp-1 mutation does not further decrease the short lifespan of daf-16 and/or hsf-1 mutants. aqp-1 transgene is expressed in pharynx and intestine (which behaves as entire endoderm of animal, including adipose tissues). Dietary glucose does not cause significant differences in levels of glucose or glycerol in wild-type vs. aqp-1 mutants [19883616].
