“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.

Two review articles were published!
“Endoplasmic Reticulum-Plasma Membrane Contact Sites” in Annual Review of Biochemistry
“The Extended-Synaptotagmins” in Biochimica et Biophysica Acta (BBA)
In these two review articles, we described the recent advances in the field of membrane contact sites, focusing on the roles of these sites in cellular lipid delivery with special emphasis on the endoplasmic reticulum (ER)-plasma membrane (PM) contact sites (Annual Review of Biochemistry) and the evolutionarily conserved family of the ER-PM tether extended-synaptotagmis (BBA).

“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.
