ProteomicsAltered GM1 catabolism affects NMDAR-mediated Ca2+ signaling at ER-PM junctions and increases synaptic spine formation
GM1-ganglioside, an abundant GSL in neuronal membranes, is integral to ER-PM junctions where it interacts with synaptic proteins/receptors and regulates Ca2+ signaling.

TranscriptomicsSecretome translation shaped by Lysosomes and Lunapark-marked ER Junctions
This study investigates how translation of mRNAs encoding membrane and secretory proteins (“secretome mRNAs”) is spatially regulated in human cells. Using live-cell imaging, proteomics, and RNA-sequencing, we show that Lunapark (LNPK)–enriched ER junctions and lysosomes form specialized hubs that en...
