Sirtuin 3 interacts with Lon protease and regulates its acetylation status

Abstract

Lon is a mitochondrial protease that degrades oxidized damaged proteins, assists protein folding and participates in maintaining mitochondrial DNA levels. Changes in Lon mRNA levels, protein levels and activity are not always directly correlated, suggesting that Lon could be regulated at post translational level. We found that Lon and SIRT3, the most important mitochondrial sirtuin, colocalize and coimmunoprecipitate in breast cancer cells, and silencing or inhibition of Lon did not alter SIRT3 levels. Silencing of SIRT3 increased the levels of Lon protein and of its acetylation, suggesting that Lon is a target of SIRT3, likely at K917.
