ctl-1 encodes one of three C. elegans catalases; CTL-1 exhibits catalase activity in vitro, and thus likely functions in vivo as an antioxidant enzyme that protects cells from reactive oxygen species; ctl-1 activity contributes to the extended lifespan seen in daf-2 mutant animals; in addition, ctl-1 expression is negatively regulated by DAF-2-mediated insulin signaling; as CTL-1 does not possess a C-terminal peroxisomal targeting signal (PTS), it is predicted to be a cytosolic catalase.
Enables catalase activity. Predicted to be involved in hydrogen peroxide catabolic process and response to hydrogen peroxide. Predicted to be located in mitochondrion and peroxisome. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); eye disease (multiple); and lung disease (multiple). Is an ortholog of human CAT (catalase).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
