OrganismCaenorhabditis elegans
Aging PhenotypeNo effect on life-span
Allele TypeRecessive
StrainBristol N2
DescriptionMutation of daz-1 has no effect on life span (Arantes-Oliviera et al., 2002).
Gene FunctionMeiotic factor required for oogenesis.
Other Phenotypesdaz-1 mutants are sterile and have a gonad that contains small nuclei and no oocytes (Karashima et al., 2000). Sperm production is normal. Oocyte precursors arrest at meiotic prophase and undergo apoptosis.
