High local concentrations of glycine receptors (GlyRs) at inhibitory postsynaptic sites are achieved through their binding to the scaffold protein gephyrin. The N- and C-terminal domains of gephyrin are believed to trimerize and dimerize, respectively, thus contributing to the formation of submembranous gephyrin clusters at synapses. GlyRs are associated(More)
Single-particle tracking (SPT) applications have been growing rapidly in the field of cell biology, and in particular in neurobiology, as a means of unravelling the involvement of diffusion dynamics of neurotransmitter receptors and other synaptic proteins in the regulation of neuronal activity. Suitable probes and technological improvements make SPT more(More)
In Myxococcus xanthus the gliding motility machinery is assembled at the leading cell pole to form focal adhesions, translocated rearward to propel the cell, and disassembled at the lagging pole. We show that MglA, a Ras-like small G-protein, is an integral part of this machinery. In this function, MglA stimulates the assembly of the motility complex by(More)
