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

PRKDC is involved in DNA repair and may modulate transcription [554]. Evidence also suggests PRKDC may be involved in telomere biology [557]. DNA breaks activate PRKDC in mouse skeletal muscle, which then goes on to phosphorylate HSP90AA1, decreasing its function as a chaperone. This suppresses mitochondrial function, energy metabolism, and physical fitness. Therefore, accumulation of DNA breaks in ageing may be one of the drivers of metabolic and fitness decline due to increased PRKDC activity [4507].

Because PRKDC has been associated with many pathways with genes likely to be involved in human ageing, such as WRN [558], it is possible that PRKDC itself is involved in human ageing, though further research is necessary to investigate this hypothesis.
