OrganismCaenorhabditis elegans
Aging PhenotypeLife-span extension
Allele TypeRecessive
StrainBristol N2
DescriptionIncreases hermaphrodite life span by approximately 70% and increases male life span by 150% (Ailion et al. 1999; Ailion and Thomas 2000; Gems and Riddle 2000).
Gene FunctionSyntaxin homolog that interacts with synaptobrevin (Ogawa et al., 1998; Saifee et al. 1998).
Other PhenotypesMutants are uncoordinated (Brenner, 1974) and exhibit a dauer constitutive phenotype (Ailion et al., 2000).
