Transcription regulatory networks in Caenorhabditis elegans

Gene

Public Gene Name

aqp-1  

Sequence Name

F32A5.5  

WB ID

WBGene00000169  

Description

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.
