Self-clearance mechanism of mitochondrial E3 ligase MARCH5 contributes to mitochondria quality control.

Abstract excerpt

MARCH5, a mitochondrial E3 ubiquitin ligase, controls mitochondrial dynamics proteins and misfolded proteins, and has been proposed to play a role in mitochondria quality control. However, it remains unclear how mutant MARCH5 found in cancer tissues is removed from cells. Here, we show that mutation in the MARCH5 ligase domain increased its half-life fourfold, resulting in a drastic increase in its protein level....
