Staying in Healthy Contact: How Peroxisomes Interact with Other Cell Organelles

Trends Mol Med. 2020 Feb;26(2):201-214. doi: 10.1016/j.molmed.2019.09.012. Epub 2019 Nov 11.


Peroxisomes share extensive metabolic connections with other cell organelles. Membrane contact sites (MCSs) establish and maintain such interactions, and they are vital for organelle positioning and motility. In the past few years peroxisome interactions and MCSs with other cellular organelles have been explored extensively, resulting in the identification of new MCSs, the tethering molecules involved, and their functional characterization. Defective tethering and compartmental communication can lead to pathological conditions that can be termed 'organelle interaction diseases'. We review peroxisome-organelle interactions in mammals and summarize the most recent knowledge of mammalian peroxisomal organelle contacts in health and disease.

Keywords: autophagy; endoplasmic reticulum; membrane contact sites; mitochondria; organelle interaction; peroxisomes.
