Synapse elimination is crucial for precise neural circuit formation during postnatal development. We examined how relative differences in synaptic strengths among competing inputs and/or absolute synaptic strengths contribute to climbing fiber (CF) to ...

The Stargazin-Related Protein {gamma}7 Interacts with the mRNA-Binding Protein Heterogeneous Nuclear Ribonucleoprotein A2 and Regulates the Stability of Specific mRNAs, Including CaV2.2 [PDF]
The role(s) of the novel stargazin-like {gamma}-subunit proteins remain controversial. We have shown previously that the neuron-specific {gamma}7 suppresses the expression of certain calcium channels, particularly CaV2.2, and is therefore unlikely to ...

Protein kinase C regulates AMPA receptor auxiliary protein Shisa9/CKAMP44 through interactions with neuronal scaffold PICK1 [PDF]
Synaptic α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptors are essential mediators of neurotransmission in the central nervous system. Shisa9/cysteine-knot AMPAR modulating protein 44 (CKAMP44) is a transmembrane protein recently found ...

Human neuronal stargazin-like proteins, gamma(2), gamma(3) and gamma(4); an investigation of their specific localization in human brain and their influence on Ca(V)2.1 voltage-dependent calcium channels expressed in Xenopus oocytes [PDF]
Background: Stargazin (gamma(2)) and the closely related gamma(3), and gamma(4) transmembrane proteins are part of a family of proteins that may act as both neuronal voltage-dependent calcium channel (VDCC) gamma subunits and transmembrane alpha-amino-3 ...

Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

The regulation of dendritic arbor development and plasticity by glutamatergic synaptic input: a review of the synaptotrophic hypothesis [PDF]
: The synaptotropic hypothesis, which states that synaptic inputs control the elaboration of dendritic (and axonal) arbors was articulated by Vaughn in 1989. Today the role of synaptic inputs in controlling neuronal structural development remains an area

Contribution of the Global Subunit Structure and Stargazin on the Maturation of AMPA Receptors [PDF]
Subunit assembly governs regulation of AMPA receptor (AMPA-R) synaptic delivery and determines biophysical parameters of the ion channel. However, little is known about the molecular pathways of this process. Here, we present single-particle EM three-dimensional structures of dimeric biosynthetic intermediates of the GluA2 subunit of AMPA-Rs ...

Long-term potentiation in bone – a role for glutamate in strain-induced cellular memory? [PDF]
Background The adaptive response of bone cells to mechanical strain is a primary determinant of skeletal architecture and bone mass. In vivo mechanical loading induces new bone formation and increases bone mineral density whereas disuse, immobilisation ...

The synaptic vesicle cluster as a controller of pre‐ and postsynaptic structure and function
Abstract figure legend The synaptic vesicle cluster acts as a master regulator of synaptic structure and function, through various involvements in processes that range from synaptic initiation to plasticity and synaptic loss. Abstract The synaptic vesicle cluster (SVC) is an essential component of chemical synapses, which provides neurotransmitter ...
