Synaptotagmin-12, a synaptic vesicle phosphoprotein that modulates spontaneous neurotransmitter release
Central synapses exhibit spontaneous neurotransmitter release that is selectively regulated by cAMP-dependent protein kinase A (PKA). We now show that synaptic vesicles contain synaptotagmin-12, a synaptotagmin isoform that differs from classical synaptotagmins in that it does not bind Ca(2+). In synaptic vesicles, synaptotagmin-12 forms a complex with synaptotagmin-1 that prevents synaptotagmi...
متن کاملRetrograde signaling by Syt 4 induces presynaptic release and synapse-specific growth.
The molecular pathways involved in retrograde signal transduction at synapses and the function of retrograde communication are poorly understood. Here, we demonstrate that postsynaptic calcium 2+ ion (Ca2+) influx through glutamate receptors and subsequent postsynaptic vesicle fusion trigger a robust induction of presynaptic miniature release after high-frequency stimulation at Drosophila neuro...
متن کاملCharacterizing Spontaneous Transient Adenosine Release
Adenosine is an important neuromodulator that regulates numerous physiological processes such as blood flow, heart rate, and neurotransmission. Traditionally, adenosine has been thought to act in a slow manner, accumulating in the extracellular space after major events such as ischemia [1]. Previous methods to study adenosine release, such as radio-labeled HPLC had good sensitivity and selectiv...
متن کاملNuclear localization of SYT, SSX and the synovial sarcoma-associated SYT-SSX fusion proteins.
Synovial sarcoma is characterized by a prevalent chromosomal translocation, t(X;18)(p11;q11). As a result of this translocation the SYT gene on chromosome 18 fuses to either the SSX1 or the SSX2 gene on the X chromosome. In this study, we generated polyclonal antibodies against the SYT and SSX2 proteins. These antibodies specifically detected both these proteins and the SYT-SSX fusion proteins ...
متن کامل12-year experience of spontaneous hemopneumothorax.
OBJECTIVES Spontaneous hemopneumothorax is a rare clinical disorder that results from a torn small vessel located in adhesions between the visceral and parietal pleurae resulting from the progress of lung collapse. A large spontaneous hemopneumothorax is often life threatening, so the late recognition and delayed intervention can increase mortality rate. PATIENTS AND METHODS From March 1994 t...
