Defect in hematopoiesis and embryonic lethality at midgestation of Vps13a/Vps13c double knockout mice

VPS13 proteins facilitate lipid transfer at membrane contact sites. VPS13A and VPS13C double knockout causes embryonic death due to impaired erythropoiesis and innate immunity activation.

The bridge-like lipid transport protein VPS13C/PARK23 mediates ER-lysosome contacts upon lysosome damage

Genetic studies link lysosome dysfunction to Parkinson's disease. VPS13C, a PD gene, relocates to damaged lysosomes, aiding in membrane repair. This process involves Rab7 and suggests early lipid transport as a protective response.

ATG2A engages Rab1a and ARFGAP1 positive membranes during autophagosome biogenesis

ATG2A aids in autophagosome formation by localizing to extra-Golgi ARFGAP1 puncta with Rab1 during early stages. Rab1 is crucial for autophagy, and disruptions in autophagosome formation lead to accumulation of ARFGAP1 and Rab1a at ectopic sites.

Membrane remodeling properties of the Parkinson’s disease protein LRRK2

Preprint: The authors examine how purified LRRK2 directly binds acidic lipid bilayers in a cell-free system and can deform them into narrow tubules in a guanylnucleotide-dependent but ATP-independent way.

Surface protein biotinylation

This protocol describes surface protein labeling with biotin using EZ-Link Sulfo-NHSLC-Biotin. This chemical reacts with primary amines such as lysine but does not  permeate cell membranes because of the charge. Thus, it only biotinylates surface…

SHIP164 is a chorein motif lipid transfer protein that controls endosome-Golgi membrane traffic

Cellular membranes differ in protein and lipid composition as well as in the protein-lipid ratio. Thus, progression of membranous organelles along traffic routes requires mechanisms to control bilayer lipid chemistry and their abundance relative to…
