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

Topoisomerases regulate the topological states of DNA [483]. Though no direct interaction has been reported, TOP2A has been indirectly linked to WRN [61] and ATM [482]. TOP2A has also been suggested as an important player in neuron proliferation [483]. Because TOP2A has been associated with several DNA metabolism proteins thought to play a role in ageing, it is possible that TOP2A itself is involved in human ageing, though further studies are necessary to confirm this hypothesis.
