Identification and characterization of roundabout orthologs in zebrafish
The Roundabout (Robo) family of receptors and their extracellular ligands, the Slit protein family, play important roles in repulsive axon guidance. First identified in Drosophila, Robo receptors form an evolutionarily conserved sub-family of the immunoglobulin (Ig) superfamily that are characterized by the presence of five Ig repeats and three fibronectin-type III repeats in the extracellular ...
متن کاملLeukoencephalopathy upon disruption of the chloride channel ClC-2.
ClC-2 is a broadly expressed plasma membrane chloride channel that is modulated by voltage, cell swelling, and pH. A human mutation leading to a heterozygous loss of ClC-2 has previously been reported to be associated with epilepsy, whereas the disruption of Clcn2 in mice led to testicular and retinal degeneration. We now show that the white matter of the brain and spinal cord of ClC-2 knock-ou...
متن کاملMolecular dissection of gating in the ClC-2 chloride channel.
The ClC-2 chloride channel is probably involved in the regulation of cell volume and of neuronal excitability. Site-directed mutagenesis was used to understand ClC-2 activation in response to cell swelling, hyperpolarization and acidic extracellular pH. Similar to equivalent mutations in ClC-0, neutralizing Lys566 at the end of the transmembrane domains results in outward rectification and a sh...
متن کاملClC-2 channels get new partners. Focus on "association between Hsp90 and the ClC-2 chloride channel upregulates channel function".
The voltage-dependent ClC-2 chloride channel has been implicated in a variety of physiological functions, including fluid transport across specific epithelia. ClC-2 is activated by hyperpolarization, weakly acidic external pH, intracellular Cl-, and cell swelling. To add more insight into the mechanisms involved in ClC-2 regulation, we searched for associated proteins that may influence ClC-2 a...
متن کاملGlialCAM, a CLC-2 Cl- Channel Subunit, Activates the Slow Gate of CLC Chloride Channels
GlialCAM, a glial cell adhesion molecule mutated in megalencephalic leukoencephalopathy with subcortical cysts, targets the CLC-2 Cl(-) channel to cell contacts in glia and activates CLC-2 currents in vitro and in vivo. We found that GlialCAM clusters all CLC channels at cell contacts in vitro and thus studied GlialCAM interaction with CLC channels to investigate the mechanism of functional act...
