We have characterized the effects of prepulse hyperpolarization and extracellular Mg 2+ on the ionic and gating currents of the Drosophila ether-à-go-go K + channel (eag). Hyperpolarizing prepulses significantly slowed channel opening elicited by a subsequent depolarization, revealing rate-limiting transitions for activation of the ionic currents.

hERG channel dysfunction can be caused by alterations in the genes encoding this channel as well as by some commonly used medications The K1 Channel Gene Ether a Go-Go Is Required for the Transduction of a Subset of Odorants in Adult Drosophila melanogaster Greg Harris The ability to identif y and discriminate among odorants is important for the survival of many animal species and depends in part on the contributions of odorant-modulated conductances to sensory cell excitability. INTRODUCTIONWe uncovered a synthetic lethal interaction between the loss of function ether-a-go-go (eag) Shaker (Sh) double mutant and the gain-offunction neural expression of the transcription factor escargot (esg) in Drosophila melanogaster through an ongoing genetic screen for genes that affect lifespan and oxidative stress sensitivity, Oxidative stress is of significant health concern as it plays a major role in determining lifespan (Finkel and Holbrook 2000). Nov 12, 2019 · Light-evoked dCRY-mediated membrane depolarization in Drosophila lateral ventral (LNv) neurons depends on potassium channel heteromultimeric complexes consisting of redox-sensing cytoplasmic potassium beta (Kvβ) HYPERKINETIC (HK) subunits and ion-conducting voltage-gated potassium alpha (Kvα) ether-a-go-go family subunits (11, 12). However, the molecular mechanism of redox coupling between dCRY and FAD leading to electrophysiological membrane potential changes remains unclear. THE Drosophila ether-à-go-go (eag) mutant is responsible for altered potassium currents in excitable tissue1. These mutants exhibit spontaneous, repetitive firing of action potentials in the example, Shaker (Sh) and ether-a-go-go (eag) mutations were isolated owing to the shaking phenotype of the legs (Kaplan and Trout, 1969).

EAG is an outward-rectifying K +-channel originally identified in the Drosophila mutant ether à go-go (Warmke et al., 1991) that exhibits a leg-moving phenotype upon ether anaesthesia. EAG has been suggested to be important for both controlling the cell cycle and/or the cell proliferation ( Pardo et al. , … Mar 23, 2010 Drosophila ether-à-go-go K 1 channel (eag). Hyperpolarizing prepulses signiﬁcantly slowed channel opening elicited by a subsequent depolarization, revealing rate-limiting transitions for activation of the ionic currents. Extracellular Mg 2 1 dramatically slowed … The shaker (Sh) gene, when mutated, causes a variety of atypical behaviors in the fruit fly, Drosophila melanogaster.

1993; Warmke and Ganetzky 1994). Antipsychotic drugs are thought to exert their therapeutic action by antagonizing dopamine receptors but are also known to produce side effects in the heart by inhibiting cardiac ether-a-go-go –related gene (ERG) K + channels. Recently, it has been discovered that the same channels are present in the brain, including midbrain dopamine neurons. Dubin et al.

The Drosophila larval nervous system thus provides a genetically tractable model to ask how ion channels influence cells in various states of proliferative potential and differentiation. Previously, our laboratory has used Drosophila to characterize a role for the voltage-gated K + channel ether-a-go- go (EAG) in tumor development ( Huang et al

1993). Sh was the first potassium channel identified and allowed the biochemical purification and molecular characterization of vertebrate potassium An Introduction to Drosophila melanogaster. Drosophila melanogaster is a small, common fly found near unripe and rotted fruit. It has been in use for over a century to study genetics and behavior. Thomas Hunt Morgan was the preeminent biologist studying Drosophila early in the 1900’s. Mar 23, 2010 · Particularly useful for such studies have been temperature-sensitive (ts) paralytic mutants including paralytic (para) and slowpoke (slo), which encode voltage-gated sodium channels and calcium-activated potassium channels, respectively, and seizure (sei), which encodes the Drosophila ortholog of the voltage-gated human ether-a-go-go-related Modulates Slow Gating and Opening of Ether-à-Go-Go K Channel is currently unknown whether this residue traverses the ﬁeld or instead inﬂuences the local potential experi-enced by the S4 residues. The Drosophila ether-à-go-go K 1 channel (eag) 1 and its vertebrate homologues constitute a unique subfamily of voltage-gated K 1 Drosophila Vials POLYSTYRENE VIALS Offer glass-like clarity for excellent visibility.

The Drosophila ether-à-go-go K + channel (eag) and its vertebrate homologues constitute a unique subfamily of voltage-gated K + channels (Warmke et al. 1991; Brüggemann et al. 1993; Warmke and Ganetzky 1994). For example, Shaker (Sh) and ether-a-go-go (eag) mutations were isolated owing to the shaking phenotype of the legs (Kaplan and Trout, 1969).

One requires no anesthetizing but quick hands. a. Place a funnel in the mouth of a fresh culture vial that already has media added. In the old vial (the one with flies in it), gently tap the flies down by softly tamping the vial on a soft surface, such as a mouse pad. Nov 01, 2015 The human ether-à-go-go-related potassium channel (hERG, Kv11.1) is a voltage-dependent channel known for its role in repolarizing the cardiac action potential. hERG alteration by mutation or pharmacological inhibition produces Long QT syndrome and the lethal cardiac arrhythmia torsade de pointes.We have determined the molecular structure of hERG to 3.8 Å using cryo-electron microscopy.

Nov 08, 2020 · eag ether a go-go [ (fruit fly)] Data suggest the dEAG channel is a docking platform for the protein kinase CaMKII and that phosphorylation of the channel's kinase recognition sequence modulates the strength of the interaction between the channel and the kinase. These results show that even a minor change in amino acid side-chain chemistry and size can have a dramatic impact on channel biophysics, and that RNA editing is important for fine-tuning eag channel's function. eag - Ether a go-go, isoform C - Drosophila melanogaster (Fruit fly) - eag gene & protein UniProtKB - M9MSD1 (M9MSD1_DROME) The K+ channel gene ether a go-go is required for the transduction of a subset of odorants in adult Drosophila melanogaster.
