Synaptic Vesicle Proteins and Active Zone Plasticity
Neurotransmitter is released from synaptic vesicles at the highly specialized presynaptic active zone (AZ). The complex molecular architecture of AZs mediates the speed, precision and plasticity of synaptic transmission. Importantly, structural and functional properties of AZs vary significantly, even for a given connection. Thus, there appear to be distinct AZ states, which fundamentally influ...
متن کاملRapid active zone remodeling during synaptic plasticity.
How can synapses change the amount of neurotransmitter released during synaptic plasticity? Although release in general is intensely investigated, its determinants during plasticity are still poorly understood. As a model for plastic strengthening of synaptic release, we here use the well-established presynaptic homeostatic compensation during interference with postsynaptic glutamate receptors ...
متن کاملFunctional Interaction of the Active Zone Proteins Munc13-1 and RIM1 in Synaptic Vesicle Priming
Synaptic neurotransmitter release is restricted to active zones, where the processes of synaptic vesicle tethering, priming to fusion competence, and Ca2+-triggered fusion are taking place in a highly coordinated manner. We show that the active zone components Munc13-1, an essential vesicle priming protein, and RIM1, a Rab3 effector with a putative role in vesicle tethering, interact functional...
متن کاملPresynaptic Active Zone Density during Development and Synaptic Plasticity
Neural circuits transmit information through synapses, and the efficiency of synaptic transmission is closely related to the density of presynaptic active zones, where synaptic vesicles are released. The goal of this review is to highlight recent insights into the molecular mechanisms that control the number of active zones per presynaptic terminal (active zone density) during developmental and...
متن کاملSynaptic vesicle proteins
What are they called? The uptake and storage of neurotransmitters is taken care of by the imaginatively named ‘neurotransmitter transporter proteins’ (as well as by ion channels and a proton ATPase). The synaptic vesicle proteins in the membrane trafficking class have mostly been given the prefix ‘synapto’, from the Latin meaning ‘to attach together’, and a suffix supposed to reflect a particul...
