[PDF][PDF] Molecular mechanisms of synaptic vesicle priming by Munc13 and Munc18

Y Lai, UB Choi, J Leitz, HJ Rhee, C Lee, B Altas… - Neuron, 2017 - cell.com
Munc13 catalyzes the transit of syntaxin from a closed complex with Munc18 into the ternary
SNARE complex. Here we report a new function of Munc13, independent of Munc18: it …

[PDF][PDF] Formation and maintenance of functional spines in the absence of presynaptic glutamate release

A Sigler, WC Oh, C Imig, B Altas, H Kawabe… - Neuron, 2017 - cell.com
Dendritic spines are the major transmitter reception compartments of glutamatergic synapses
in most principal neurons of the mammalian brain and play a key role in the function of …

[HTML][HTML] Widespread expression of erythropoietin receptor in brain and its induction by injury

…, MP Zafeiriou, UK Peteri, D Hesse, S Gerhart, B Altas… - Molecular …, 2015 - Springer
Erythropoietin (EPO) exerts potent neuroprotective, neuroregenerative and procognitive
functions. However, unequivocal demonstration of erythropoietin receptor (EPOR) expression in …

[PDF][PDF] Ultrastructural correlates of presynaptic functional heterogeneity in hippocampal synapses

L Maus, CK Lee, B Altas, SM Sertel, K Weyand… - Cell reports, 2020 - cell.com
Although similar in molecular composition, synapses can exhibit strikingly distinct functional
transmitter release and plasticity characteristics. To determine whether ultrastructural …

[PDF][PDF] Polarity acquisition in cortical neurons is driven by synergistic action of Sox9-regulated Wwp1 and Wwp2 E3 ubiquitin ligases and intronic miR-140

…, K Hori, A Salazar-Lázaro, A Rusanova, B Altas… - Neuron, 2018 - cell.com
The establishment of axon-dendrite polarity is fundamental for radial migration of neurons
during cortex development of mammals. We demonstrate that the E3 ubiquitin ligases WW-…

The murine ortholog of Kaufman oculocerebrofacial syndrome protein Ube3b regulates synapse number by ubiquitinating Ppp3cc

…, A Smorodchenko, AI Weber, HJ Rhee, B Altas… - Molecular …, 2021 - nature.com
Kaufman oculocerebrofacial syndrome (KOS) is a severe autosomal recessive disorder
characterized by intellectual disability, developmental delays, microcephaly, and characteristic …

[HTML][HTML] BDNF enhances spontaneous and activity-dependent neurotransmitter release at excitatory terminals but not at inhibitory terminals in hippocampal neurons

…, V Bharat, D Brockelt, B Altas… - Frontiers in synaptic …, 2014 - frontiersin.org
Brain-derived neurotrophic factor (BDNF) is widely reported to enhance synaptic vesicle (SV)
exocytosis and neurotransmitter release. But it is still unclear whether BDNF enhances SV …

Enhancing Precision and Efficiency of Cas9-Mediated Knockin Through Combinatorial Fusions of DNA Repair Proteins

…, AJ Romanowski, J Inen, B Altas… - The CRISPR …, 2023 - liebertpub.com
Cas9 targets genomic loci with high specificity. For knockin with double-strand break repair,
however, Cas9 often leads to unintended on-target knockout rather than intended edits. This …

Nedd4-2-dependent regulation of astrocytic Kir4. 1 and Connexin43 controls neuronal network activity

B Altas, HJ Rhee, A Ju, HC Solís, S Karaca… - Journal of Cell …, 2024 - rupress.org
Nedd4-2 is an E3 ubiquitin ligase in which missense mutation is related to familial epilepsy,
indicating its critical role in regulating neuronal network activity. However, Nedd4-2 …

[HTML][HTML] Neuronal mTOR outposts: Implications for translation, signaling, and plasticity

B Altas, AJ Romanowski, GW Bunce… - Frontiers in Cellular …, 2022 - frontiersin.org
The kinase mTOR is a signaling hub for pathways that regulate cellular growth. In neurons,
the subcellular localization of mTOR takes on increased significance. Here, we review …
