Control of lifespan in Caenorhabditis elegans by the DAF-2 insulin-like signaling pathway requires daf-16
. which encodes a member of the forkhead family of transcription factors. A new study provides evidence that DAF-2 negatively regulates DAF-16 activity by promoting its retention in the cytoplasm. But, constitutive targeting of DAF-16 to the nucleus is not sufficient to extend lifespan, revealing a new layer of complexity in the genetic control of aging in the nematode.
