OrganismCaenorhabditis elegans
Aging PhenotypeLife-span extension
Allele TypeRecessive
StrainBristol N2
DescriptionRecessive, loss of function allele can increase life span up to 100%. Life span extension is suppressed by daf-16 and gonad ablation (Apfeld and Kenyon, 1999).
Gene FunctionForms heteromeric cyclic nucleotide-gated channel along with Tax-2 (Coburn et al., 1998).
Other PhenotypesMutants are thermotaxis and chemotaxis defective (Komatsu et al., 1996; Bargmann et al., 1993). Mutants are slightly dauer constitutive and form dauers at 27C (Coburn et al., 1998).
