ProteomicsEffect of the combined loss of tomosyn (STXBP5) and tomosyn-2 (STXBP5L) on the proteome of primary mouse hippocampal neurons
Tomosyn (STXBP5) is a non-canonical SNARE protein enriched in many secretory cells and implicated in regulation of exocytosis. In neurons, loss of tomosyn affects fusion of synaptic vesicles. Here, we examined the impact of the loss of tomosyn (STXBP5) and its close paralog, tomosyn-2 (STXBP5L), on ...

ProteomicsEndo-IP and Lyso-IP Toolkit for Endolysosomal Profiling of Human Induced Neurons
We developed a toolkit for capturing endosomes (Endo-IP) and lysosomes (Lyso-IP) in human stem cell(hESC)-derived induced neurons (iNeurons). We target a sub-population of early endosomes marked by endogenously tagged EEA1 (Early Endosome Antigen 1) protein, which represents one of the earliest popu...

ProteomicsReduced mGluR5 activity modulates mitochondrial function in the synapse
The metabotropic glutamate receptor 5 (mGluR5) is a G-protein coupled receptor with an important role in synaptic function at multiple levels. In physiological conditions, mGluR5 is an essential modulator of synaptic plasticity, learning and memory; whereas in pathological conditions, it is an ackno...

ProteomicsUnbalanced protein expression contributes to pathology in Fragile X Syndrome
Dysregulated protein synthesis is a core pathogenic mechanism in Fragile X Syndrome (FX). The mGluR Theory of FX predicts that pathological synaptic changes arise from the excessive translation of mRNAs downstream of mGlu1/5 activation. Here, we use a combination of CA1 pyramidal neuron-specific Tra...

ProteomicsSHANK2A and SHANK2A(R841X) mouse brain SWATH quantitative proteomics
The high molecular complexity of the SHANK scaffold and its fundamental role in neural circuitries governing social behavior is not well understood. Here we analyzed two newly generated transgenic mouse lines with the SHANK2A wild-type isoform and the other with SHANK2A carrying a SHANK2A(R841X) poi...

ProteomicsBlue Native PAGE co-fractionation of purified human endosomes
EndoMAP aims to systematically dissect the human endosomal protein complexes. To purify endosomes from human cells, a modified Endo-IP protocol was developed to be compatible with complexomics methodologies and evaluated by DIA-MS. Three independent biological replicates of human endosomes purified ...

ProteomicsCharacterization of endosomes and interactions from TMEM230 and TMEM9/9B mutants in human neurons
EndoMAP aims to systematically dissect the human endosomal protein complexes. To examine TMEM9 and TMEM230 interactions, we generated TMEM230 and TMEM9 knockouts (KOs) using CRISPR/Cas9 in human embryonic stem (ES) cells and converted the cells to induced neurons (iNeurons). TMEM230 and TMEM9 were i...

ProteomicsBrain region differences in α1 and α5 subunit-containing GABAA receptor proteome revealed by affinity purification and Blue Native PAGE proteomics
GABAA receptors are the major inhibitory receptors in the brain. They are hetero-pentamers with a composition of predominantly two α, two β and one γ or δ subunit. From the six α subunit genes, the α5 subunit displays a limited spatial expression pattern and is known to mediate both phasic and tonic...

To capture the changes in the lysosomal proteome upon TRPML1 activation, achieved using a small molecule agonist MLSA5, human cancer cells, with or without gene-editing, stably expressing TMEM192-mRFP-3xHA (Lyso-IP), were treated with MLSA5 and Lyso-IP samples were prepared and processed for TMT-MS ...
