Protein Quality Control at the Mitochondrial Surface [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mitochondria contain two membranes, the outer and inner membrane. The outer membrane fulfills crucial functions for the communication of mitochondria with the cellular environment like exchange of lipids via organelle contact sites, the transport of metabolites and the formation of a signaling platform in apoptosis and innate immunity.
