OVER THE PAST DECADE, COMMD1 (copper metabolism MURR1 domain containing protein 1) has been regularly identified to interact with ion transport proteins. What do we know about COMMD1, and is there a common ion transport regulatory role for COMMD1? COMMD1 is evolutionarily conserved, and codes for a 21-kDa protein composed of two domains: a COOH-terminal COMM domain found in nine other COMMD pro...
Benzodiazepine receptor agonists are widely prescribed therapeutic agents that alter gamma-aminobutyric acid (GABA)A activity and have anxiolytic effects. Post-operative use of benzodiazepines is a risk factor delirium. Inflammatory conditions the effects benzodiazepine. We investigated effect diazepam, typical benzodiazepine anxiolytic, on changes in emotional behavior mice hole-board test aft...
Alterations in the balance of K-Na-2Cl cotransporter (NKCC1) and Na-Cl cotransporter (KCC2) activity may cause depolarizing effect of γ-aminobutyric Acid (GABA), and contribute to epileptogenesis in human temporal lobe epilepsy. NKCC1 facilitates accumulation of chloride inside neurons and favors depolarizing responses to GABA. In the current pilot study we provide the first documented look at ...
In vertebrate olfactory receptor neurons (ORNs), the odorant-triggered receptor current flows through two distinct ion channels on the sensory cilia: Ca2+ influx through a cyclic nucleotide-gated (CNG) channel followed by Cl- efflux through a Ca2+-activated anion channel. The excitatory Cl- current amplifies the small CNG current and crucially depends on a high intracellular Cl- concentration. ...
γ-Aminobutyric acid (GABA) is the main inhibitory neurotransmitter of the mature central nervous system (CNS). The developmental switch of GABAergic transmission from excitation to inhibition is induced by changes in Cl(-) gradients, which are generated by cation-Cl(-) co-transporters. An accumulation of Cl(-) by the Na(+)-K(+)-2Cl(-) co-transporter (NKCC1) increases the intracellular Cl(-) con...
Cell shrinkage phosphorylates and activates the Na-K-2Cl cotransporter (NKCC1), indicating the presence of a volume-sensitive protein kinase. To identify this kinase, extracts of normal and shrunken aortic endothelial cells were screened for phosphorylation of NKCC1 fusion proteins in an in-the-gel kinase assay. Hypertonic shrinkage activated a 46-kDa kinase that phosphorylated an NH2-terminal ...
Threonines targeted by Ste20-related proline-alanine-rich kinase (SPAK) for phosphorylation have been identified in Na+-K+-2Cl(-) cotransporter type 1 (NKCC1), NKCC2, and Na+-Cl(-) cotransporter (NCC). However, what constitutes the substrate recognition of the kinase is still unknown. Using site-directed mutagenesis and functional measurement of NKCC1 activity in Xenopus laevis oocytes, we dete...
Early in development, GABA, an inhibitory neurotransmitter in adults, is excitatory. NKCC1 (SLC12A2) encodes one of two cation chloride cotransporters mediating the conversion of GABA from excitatory to inhibitory. Using 3' and 5' RACE and PCR, we verified previously characterized alternative transcripts of NKCC1a (1-27) and NKCC1b (1-27(Δ21)), identified new NKCC1 transcripts, and explored the...
Polymorphisms in the gene encoding sterile 20/SPS1-related proline/alanine-rich kinase (SPAK) associate with hypertension susceptibility in humans. SPAK interacts with WNK kinases to regulate the Na(+)-K(+)-2Cl(-) and Na(+)-Cl(-) co-transporters [collectively, N(K)CC]. Mutations in WNK1/4 and N(K)CC can cause changes in BP and dyskalemia in humans, but the physiologic role of SPAK in vivo is un...
The loop diuretic bumetanide (Bumex) is thought to have antiepileptic properties via modulate GABAA mediated signaling through their antagonism of cation-chloride cotransporters. Given that loop diuretics may act as antiepileptic drugs that modulate GABAergic signaling, we sought to investigate whether they also affect hippocampal function. The current study was performed to evaluate the possib...
