CaMKIIalpha interacts with multi-PDZ domain protein MUPP1 in spermatozoa and prevents spontaneous acrosomal exocytosis [PDF]
The success of acrosomal exocytosis, a complex process with a variety of inter-related steps, relies on the coordinated interaction of participating signaling molecules.

Ca2+ sensor synaptotagmin-1 mediates exocytosis in mammalian photoreceptors
To encode light-dependent changes in membrane potential, rod and cone photoreceptors utilize synaptic ribbons to sustain continuous exocytosis while making rapid, fine adjustments to release rate.

Tyrosine kinase inhibition produces specific alterations in axon guidance in the grasshopper embryo [PDF]
Tyrosine kinase signaling pathways are essential for process outgrowth and guidance during nervous system development. We have examined the roles of tyrosine kinase activity in programming growth cone guidance decisions in an intact nervous system in ...

PRRT2 Is a Key Component of the Ca2+-Dependent Neurotransmitter Release Machinery
Heterozygous mutations in proline-rich transmembrane protein 2 (PRRT2) underlie a group of paroxysmal disorders, including epilepsy, kinesigenic dyskinesia, and migraine.

Synaptotagmin I, a molecular target for steroid hormone signaling controlling the maturation of sexual behavior in an insect [PDF]
As in vertebrates, the insect steroid hormones, especially 20-hydroxyecdysone (20E), initiate and regulate sexual behavior by acting on the central nervous system.

Phosphatidylinositol 4,5 bisphosphate controls the cis and trans interactions of synaptotagmin 1
Synaptotagmin 1 acts as the Ca2+-sensor for synchronous neurotransmitter release; however, the mechanism by which it functions is not understood and is presently a topic of considerable interest.

Genomic Analysis of Synaptotagmin Genes
I used TBLASTn to probe DNA sequence databases with a consensus peptide sequence corresponding to the most highly conserved region of the rodent synaptotagmin (Syt) gene family, which is within the C2B domain. I found human homologues for all known rodent genes, and found six further human genomic loci which encode potential family members.

Synaptotagmin 7 confers frequency invariance onto specialized depressing synapses
At most synapses in the brain, short-term plasticity dynamically modulates synaptic strength. Rapid frequency-dependent changes in synaptic strength have key roles in sensory adaptation, gain control and many other neural computations.

Synaptotagmin 4: A New Antiobesity Target? [PDF]
In this issue of Neuron, Zhang et al. show that Synaptotagmin 4 (Syt4) is specifically induced in adult hypothalamic oxytocin neurons by high-fat diet. Evidence is provided to support a critical role for Syt4 in negative regulation of oxytocin release, which in turn is responsible for diet-induced obesity, raising the possibility of using Syt4 as a new

Wnt signalling tunes neurotransmitter release by directly targeting Synaptotagmin-1 [PDF]
The functional assembly of the synaptic release machinery is well understood; however, how signalling factors modulate this process remains unknown. Recent studies suggest that Wnts play a role in presynaptic function. To examine the mechanisms involved,
