The aim of the present project was to identify putative substrates of Ariadne-1 (Ari-1), an essential E3 ubiquitin-ligase, in Drosophila heads. For that purpose we combined an in vivo ubiquitin biotinylation strategy termed bioUb with label free mass spectrometry analysis. In brief, BioUb strategy r...

Analysis of a long noncoding RNAs that modulate neurotransmitter release
The functions of many human proteins remain unknown, highlighting major gaps in our understanding of cellular biology. TTC33 is an evolutionarily conserved tetratricopeptide repeat (TPR) protein expressed across human tissues, whose molecular role is not defined. Here we identify the TTC33 partners ...

Cross-Platform Validation of Neurotransmitter Release Impairments in Schizophrenia Patient-Derived NRXN1-Mutant Neurons
Neuronal communication relies on neurotransmitter release from synaptic vesicles (SVs), whose dynamics are controlled by Ca2+-dependent pathways, as many thoroughly studied phosphorylation cascades. However, little is known about other post-translational modifications, as ubiquitination. To address ...
ORGANISM(S): Homo Sapiens Rattus Norvegicus 
Glud1 (glutamate dehydrogenase 1) transgenic mice release more excitatory neurotransmitter glutamate to synaptic cleft throughout lifespan and show signs of accelerated aging. Here we compared transcriptomic profiles of these animals to their wild-type counterparts. The hippocampus was used for the ...
ORGANISM(S): Mus musculus 
Heterozygous NRXN1 deletions constitute the most prevalent currently known single-gene mutation associated with schizophrenia, and predispose to multiple other neurodevelopmental disorders. Previous studies showed that engineered heterozygous NRXN1 deletions impaired neurotransmitter release in huma...
