[HTML][HTML] The role of α-synuclein in SNARE-mediated synaptic vesicle fusion

G Yoo, YK Shin, NK Lee - Journal of molecular biology, 2023 - Elsevier

Synaptotagmin 1 clamps synaptic vesicle fusion in mammalian neurons independent of complexin

NA Courtney, H Bao, JS Briguglio… - Nature …, 2019 - nature.com
Synaptic vesicle (SV) exocytosis is mediated by SNARE proteins. Reconstituted SNAREs
are constitutively active, so a major focus has been to identify fusion clamps that regulate …

Synaptotagmin-1 binds to PIP2-containing membrane but not to SNAREs at physiological ionic strength

Y Park, JB Seo, A Fraind, A Pérez-Lara… - Nature structural & …, 2015 - nature.com
Abstract The Ca2+ sensor synaptotagmin-1 is thought to trigger membrane fusion by binding
to acidic membrane lipids and SNARE proteins. Previous work has shown that binding is …

Synaptotagmin-1 membrane binding is driven by the C2B domain and assisted cooperatively by the C2A domain

C Gruget, O Bello, J Coleman, SS Krishnakumar… - Scientific Reports, 2020 - nature.com
Synaptotagmin interaction with anionic lipid (phosphatidylserine/phosphatidylinositol)
containing membranes, both in the absence and presence of calcium ions (Ca2+), is critical …

Ring-like oligomers of Synaptotagmins and related C2 domain proteins

MN Zanetti, OD Bello, J Wang, J Coleman, Y Cai… - Elife, 2016 - elifesciences.org
We recently reported that the C2AB portion of Synaptotagmin 1 (Syt1) could self-assemble
into Ca2+-sensitive ring-like oligomers on membranes, which could potentially regulate …

Synaptotagmin-1 C2B domains cooperatively stabilize the fusion stalk via a master-servant mechanism

AL Di Bartolo, D Masone - Chemical Science, 2022 - pubs.rsc.org
Synaptotagmin-1 is a low-affinity Ca2+ sensor that triggers synchronous vesicle fusion. It
contains two similar C2 domains (C2A and C2B) that cooperate in membrane binding, being …

Human transposons are an abundant supply of transcription factor binding sites and promoter activities in breast cancer cell lines

JC Jiang, KR Upton - Mobile DNA, 2019 - Springer
Background Transposable elements (TE) are commonly regarded as “junk DNA” with no
apparent regulatory roles in the human genome. However, a growing body of evidence …

The synaptotagmin-1 C2B domain is a key regulator in the stabilization of the fusion pore

M Caparotta, CN Tomes, LS Mayorga… - Journal of Chemical …, 2020 - ACS Publications
