eMags is an engineered photodimerizer pair for optogenetic modulation in mammalian cells that is especially suited for the manipulation of intracellular processes occurring in small volumes or subcellular organelles.

To establish membrane contacts between its vacuole and the endoplasmic reticulum, the obligate intracellular bacterial pathogen Chlamydia trachomatis has evolved complex molecular strategies to mimic emerging regulatory processes that control contact-dependent organelle–organelle communication.

ABHD16A is a phospholipid-modifying endoplasmic reticulum (ER) membrane protein required for both mitochondrial fission and fusion machinery recruitment to ER-associated mitochondrial constrictions.

High-throughput analysis of several Saccharomyces cerevisiae contact sites reveals a large data set of potential contact site proteins, including proteins involved in the regulation of lipid distribution within cells.

Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.

A reanalysis of the stochastic model of organelle production (Mukherji and O'Shea, 2014) suggests that this model requires significant further discussion.

A new family of sterol-specific lipid transfer proteins has been found that anchors in the endoplasmic reticulum; some of these proteins stretch across membrane contacts and mediate sterol traffic from the plasma membrane.

A crucial step during the mitophagy cascade involves the disassembly of connections between mitochondria and the endoplasmic reticulum via the retrotranslocation of Mfn2 tethering complexes by the Parkinson's disease genes PARKIN and PINK1, as well as the ATPase VCP/p97.

A combination of an in vitro mitochondrial fusion assay with electron cryo-tomography (cryo-ET) reveals distinct steps and protein complexes during mitofusin-dependent fusion between adjacent mitochondrial outer membranes.

An unbiased separation method reveals distinct subpopulations of insulin secretory vesicles that undergo dynamic remodeling upon glucose stimulation.
