The role of organelle-contact sites in lipid transport

Abstract

Organelles compartmentalize specific sets of enzymes and metabolites, enabling them to perform their characteristic functions. Due to this functional specialization, organelles have long been considered spatially independent structures. However, recent research has identified membrane contact sites (MCS), regions where different organelle membranes are directly connected, revealing that organelles collaborate more closely than previously thought. The discovery of MCS has introduced a paradigm shift in organelle research, offering a new perspective on how organelles function. In this article, I will provide an overview of the latest trends in MCS research, with a particular focus on the mechanisms of lipid transport via MCS in yeast.
