| Description | The original results (below) associating mutation of ctl-1 with increased life-span have been retracted (Taub et al., 2003). The relationship between catalase activity and life-span, if any, is currently unclear. --------------------------RETRACTED-------------------------- Loss of function shortens life span to 77% of wild type animals. Mutants accumulate fluorescent material faster than wild type, suggesting accelerated aging. Ctl-1 mutation prevents life span extension by daf-2 or clk-1 (Taub et al., 1999). --------------------------RETRACTED--------------------- |

| Gene Function | Cytosolic catalase. |
|---|
| Other Phenotypes | Mutation of ctl-1 reduces catalase activity by 50% (Taub et al., 1999). |
