Regulation and physiology of membrane contact sites

Membrane contact sites (MCSs) in addition to impacting the functions of membrane-limited organelles also have a role in the spatial and functional organization of cells, tissues and whole organisms. MCSs have been identified between all organelles and the identification of their molecular composition has progressed significantly in recent years. Equally important is how MCSs respond dynamically to physiological stimuli, how this is regulated, and the physiological roles of MCSs in tissues and at the organismal level, an area that still remains relatively unexplored. In the present review, we focus on the regulation of MCSs, considerations of their function at the organismal level, and how mutations of MCS components linked to genetic diseases might inform us about their physiological relevance.

Automated summary

This review focuses on the regulation and physiological roles of membrane contact sites (MCSs) in cells, tissues, and whole organisms. It discusses the dynamic response of MCSs to physiological stimuli, their molecular composition, and how mutations of MCS components related to genetic diseases can provide insights into their physiological relevance.
