Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description

CLOCK forms a heterodimer with ARNTL, which activates circadian rhythm-associated genes. Mice deficient in ARNTL have an impaired circadian behavior, reduced lifespan, and display symptoms of premature ageing associated in some tissues with increased levels of reactive oxygen species [1841][2134]. CLOCK mutant mice do not display predisposition to tumour formation. When challenged with low-dose irradiation, however, they appear to accelerate their ageing program and develop a phenotype reminiscent of ARNTL-deficient mice [1842]. ARNTL and CLOCK also appear to be involved in the response to genotoxic stress [1868]. Overall, CLOCK might play some role in mammalian ageing.
