Regulated membrane trafficking of AMPA-type glutamate receptors (AMPARs) is a key mechanism underlying synaptic plasticity, yet the pathways used by AMPARs are not well understood. In this paper, we show that the AMPAR subunit GLR-1 in Caenorhabditis elegans utilizes the retrograde transport pathway to regulate AMPAR synaptic abundance. Mutants for rab-6.2, the retromer genes vps-35 and snx-1, ...
Ionotropic glutamate receptors (iGluRs) in Caenorhabditis elegans are predicted to have high permeability for Ca2+ because of glutamine (Q) residues in the pore loop. This contrasts to the low Ca2+ permeability of similar iGluRs in principal neurons of mammals, because of an edited arginine (R) at the critical pore position in at least one channel subunit. Here, we introduced the R residue into...
Currently, statistical techniques for analysis of microarray-generated data sets have deficiencies due to limited understanding of errors inherent in the data. A generalized likelihood ratio (GLR) test based on an error model has been recently proposed to identify differentially expressed genes from microarray experiments. However, the use of different error structures under the GLR test has no...
The regulation of AMPA-type glutamate receptor (AMPAR) membrane trafficking is a key mechanism by which neurons regulate synaptic strength and plasticity. AMPAR trafficking is modulated through a combination of receptor phosphorylation, ubiquitination, endocytosis, and recycling, yet the factors that mediate these processes are just beginning to be uncovered. Here we identify the ubiquitin-conj...
The mushroom Ganoderma lucidum (G. lucidum) has been consumed in China as a medicine for promoting health and longevity for thousands of years. Due to its paramount and multiple pharmaceutical effects, G. lucidum has received considerable attention from researchers and its chemical constituents as well as their respective functions were gradually unveiled by using modern research methods. Herei...
Area-restricted search (ARS) is a foraging strategy used by many animals to locate resources. The behavior is characterized by a time-dependent reduction in turning frequency after the last resource encounter. This maximizes the time spent in areas in which resources are abundant and extends the search to a larger area when resources become scarce. We demonstrate that dopaminergic and glutamate...
Axon specification is a critical step in neuronal development, and the function of glial cells in this process is not fully understood. Here, we show that C. elegans GLR glial cells regulate axon specification of their nearby GABAergic RME neurons through GLR-RME gap junctions. Disruption of GLR-RME gap junctions causes misaccumulation of axonal markers in non-axonal neurites of RME neurons and...
LIN-10 Is a Shared Component of the Polarized Protein Localization Pathways in Neurons and Epithelia
We tested the model that neurons and epithelial cells use a shared mechanism for polarized protein sorting by comparing the pathways for localizing basolateral and postsynaptic proteins in C. elegans. GLR-1 glutamate receptors are localized to postsynaptic elements of central synapses and, when ectopically expressed, to basolateral membranes of epithelial cells. Proper localization of GLR-1 in ...
We discuss generalisations of bottom up parsing, emphasising the relative costs for real programming languages. Our goal is to provide a roadmap of the available approaches in terms of their space and time performance for programming language applications, focusing mainly on GLR style algorithms. It is well known that the original Tomita GLR algorithm fails to terminate on hidden left recursion...
