Our lab's new research article "PDZD-8 and TEX-2 regulate endosomal PI(4,5)P2 homeostasis via lipid transport to promote embryogenesis in C. elegans" is now published in Nature Communications.
Cellular membranes maintain distinct lipid compositions that are important for their functional identity. Using the C. elegans embryo as our model system, we show that lipid transfer proteins (PDZD-8 and TEX-2) and phosphatases (UNC-26/synaptojanin and OCRL-1) work together to prevent the build-up of plasma membrane-enriched lipid, PI(4,5)P2, on endosomal membranes. In their absence, PI(4,5)P2 accumulates on endosomal membranes, disrupting cytokinesis. Mutations synaptojanin and OCRL1 in human are linked to Parkinson’s disease and Lowe syndrome. Thus, manipulating the activity of the lipid transfer proteins may help to improve these conditions.

Our lab's new research article "INPP5K and Atlastin-1 maintain the nonuniform distribution of ER–plasma membrane contacts in neurons" is now published in Life Science Alliance.
We visualized neuronal ER-plasma membrane (PM) contacts in vivo using C. elegans as a model system. By conducting forward genetic screen, we found INPP5K and Atlastin-1 that have been linked to intellectual disability and hereditary spastic paraplegia function together to maintain somatodendritic enrichment of neuronal ER-PM contacts. Further, we found that neurons with reduced activities of these proteins showed impairment in axon regeneration. Our results suggest the critical role of the nonuniform distribution of neuronal ER-PM contacts in neuronal resilience against neuronal damage.

Our lab's new research article "Molecular basis of accessible plasma membrane cholesterol recognition by the GRAM domain of GRAMD1b" is now published in The EMBO Journal.
GRAMD1 proteins are evolutionarily conserved endoplasmic reticulum (ER)-anchored sterol transporters that sense a transient increase in accessible plasma membrane (PM) cholesterol and facilitate its extraction and transport to the ER to maintain cholesterol homeostasis. Here, we identify that the GRAM domain of GRAMD1b possesses distinct sites that each contribute to sensing cholesterol and anionic lipids, including phosphatidylserine (PS), within the inner leaflet of the PM bilayer and fine-tunes GRAMD1b-mediated ER-PM tethering and accessible cholesterol transport.

Our lab's first research article "Movement of accessible plasma membrane cholesterol by GRAMD1 lipid transfer protein complex" was published in eLife.
In this work, we characterized an evolutionarily conserved family of endoplasmic reticulum (ER)-anchored lipid transfer proteins, namely GRAMD1 proteins, using mammalian cell culture and in vitro biochemical analysis. We found that GRAMD1 proteins bind one another, sense a transient expansion of the accessible pool of plasma membrane (PM) cholesterol and facilitate its delivery to the ER at ER-PM contact sites, thereby maintaining PM cholesterol homeostasis. Since ~80% of cellular cholesterol is enriched in the PM, but its biosynthesis occurs entirely in the ER, such PM to ER communication helps the cells to monitor PM cholesterol levels and regulate cholesterol biosynthesis in the ER in order to prevent cholesterol over-accumulation.

“Ca2+ releases E-Syt1 autoinhibition to couple ER-plasma membrane tethering with lipid transport.” was published in The EMBO Journal.
In this paper, we described the mechanisms that control ER-plasma membrane tethering and lipid transfer mediated by the extended synaptotagmin 1 (E-Syt1). We found that Ca2+ releases C2-domain dependent E-Syt1 autoinhibition to couple tethering and lipid transfer. As E-Syts are evolutionarily conserved across all eukaryotic cells, our study highlights the critical role of such coupling in the regulation of non-vesicular lipid transport at membrane contact sites.

“Endosome-ER Contacts Control Actin Nucleation and Retromer Function through VAP-Dependent Regulation of PI4P” was published in Cell.
In this paper, we described the cellular function of VAP protein, which is mutated in a familial form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease and motor neuron disease. VAP protein is a ubiquitously expressed endoplasmic reticulum (ER) protein that plays a pleiotropic role in cellular lipid homeostasis. Our findings revealed its novel function in lipid regulation at ER-endosome contact sites. In the absence of VAP, the levels of a particular lipid, called PI4P, dramatically increase in endosomes. This PI4P increase leads to abnormal actin nucleation and intermixing of endosomes and the Golgi via disrupted retromer function. The newly identified VAP function might be critical in the pathogenesis of ALS. This project was performed in collaboration with ALS consortium initiated by Biogen Idec, a biotechnology company in Boston.

“Control of plasma membrane lipid homeostasis by the extended synaptotagmins” was published in Nature Cell Biology.
In this paper, Yasunori and his co-researchers described the mechanisms that counteract the acute lipid changes in the plasma membrane, the key cellular membrane that encapsulates our cells from the external environment. Human cells are often exposed to environmental stimuli that induce rapid changes in plasma membrane lipid compositions. These plasma membrane lipid changes need to be reset to the normal state in order for the cells to survive and respond appropriately to subsequent stimuli. The mechanisms that are described in this paper are likely to be conserved in other cell types including neuronal cells and potentially involved in the maintenance of neuronal plasma membranes that are essential for neurotransmission and the brain function. Failure to achieve lipid homeostasis in neurons may lead to neurological disorders including Alzheimer’s disease and Parkinson’s disease.
