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. These fly vials are safe and a cost-saving alternative to … Continue Reading » activating/fast-inactivating potassium channels. In Drosophila, these are coded for by the genes: Slowpoke (abbrev. slo), Small Conductance Calcium-Activated K+ (SK), Shaker, Shal, and Ether-a-go-go (eag).

Slow activation and rapid C-type inactivation produce inward rectification of the current-voltage relationship for human ether-a'-go-go-related gene (hERG) channels. To characterize the voltage sensor movement associated with hERG activation and inactivation, we performed an Ala scan of the 32 amino acids (Gly514-Tyr545) that comprise the S4 domain and the flanking S3–S4 and S4–S5 linkers

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).

3. After a few days, the Drosophila will mate and finally the female Drosophila will lay eggs which then will hatch. The hERG gene is the human homolog of the Ether-à-go-go gene found in the Drosophila fly; Ether-à-go-go was named in the 1960s by William D. Kaplan and William E. Trout, III, while at the City of Hope Hospital in Duarte, California. 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. Keywords: ether a go-go, eag, potassium channel, Drosophila, electroantennogram, specific, Ca 2+, cyclic nucleotide analogs, mutant, olfaction The ability to identify 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 eag - Ether a go-go, isoform B - Drosophila melanogaster (Fruit fly) - eag gene & protein UniProtKB - Q0KHS8 (Q0KHS8_DROME) The Drosophila voltage-activated K ϩ channel ether a go-go (eag) (Kaplan and Trout, 1969;Drysdale et al., 1991;Warmke et al., 1991) contains a consensus CN-binding site (Guy et al., 1991). A number of independent mutations in eag appear to disrupt CN-dependent effects on K ϩ conductances in muscle (Zhong and Wu, 1993).

These channels are structurally related but … example, Shaker (Sh) and ether-a-go-go (eag) mutations were isolated owing to the shaking phenotype of the legs (Kaplan and Trout, 1969). Subsequently, further characterization of these mutants using NMJ electrophysiological recordings revealed that the mutations affect potassium channel function (Jan et al., 1977; Wu et al., 1983). 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 May 30, 2011 Dubin et al. • Ether a Go-Go,a Drosophila Olfactory Mutant J.

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). 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. • Ether a Go-Go,a Drosophila Olfactory Mutant J.

Sci. p38 MAPK regulates the expression of ether à go-go potassium channel in human osteosarcoma cells. Xinyu Wu , Daixing Zhong , Bin Lin , Wenliang Zhai Ether-a-go-go-related gene potassium channel 1; Ether-a-go-go-related protein 1 of potassium channel genes related to eag in Drosophila and mammals. Aberrant expression of ether à go-go potassium channel in colorectal cancer kinetics between the Drosophila channel and its mammalian counterpart. HERG (human ether-a-go-go-related gene-Kv6) is a voltage-dependent human K channel, closely related to the ether-a-go-go Drosophila gene and the The ether-a-go-go (eag) K+ channel family was identified in Drosophila melanogaster in mutagenesis experiments.1 The search for mammalian homologues 21 Feb 2012 hERG - human Ether-à-go-go Related Gene what?!? Yup. Biologists love a good play on words.

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.

Sh was the first potassium channel identified and allowed the biochemical purification and molecular characterization of vertebrate potassium An Introduction to Drosophila melanogaster.

The hERG gene is the human homolog of the Ether-à-go-go gene found in the Drosophila fly; Ether-à-go-go was named in the 1960s by William D. Kaplan and

The editing pattern of some sites, for example ether-a-go-go site 4 and shab site 4, changes very little due to decreased levels of dADAR.

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). Subsequently, further characterization of these mutants using NMJ electrophysiological recordings revealed that the mutations affect potassium channel function ( Jan et al., 1977 ; Wu et al., 1983 ). The human ether-a-go-go-related gene, also known to code for the hERG channel, is one of the ion channels that contribute to LQTS.
