靶點詳情

功能：

Voltage-gated potassium channel that mediates transmembrane potassium transport in excitable membranes. The channel alternates between opened and closed conformations in response to the voltage difference across the membrane. Forms rapidly inactivating tetrameric potassium-selective channels through which potassium ions pass in accordance with their electrochemical gradient and may contribute to A-type currents. Plays a role in the regulation of sleep need or efficiency. Plays a role in sexual behavior, where it is imortant for male sex discrimination.

1. S4-S5 linker movement during activation and inactivation in voltage-gated K(+) channels. PMID: 29959207
2. Authors provide evidence that in the Drosophila Shaker voltage-gated K(+) channels the S3 domain acts as an extracellular hydrophobic 'stabilizer' for the S4 domain biasing the gating chemical equilibrium toward the open state. PMID: 23542156
3. This study demonstrates that Shaker is not always a good model for Kv1 channels for ligand binding. PMID: 23398369
4. The xenon requirement in Drosophila melanogaster is not influenced by a single gene mutation at the shaker locus, whereas a reduced expression of a nonselective cation channel leads to an increased xenon requirement. PMID: 22761550
5. Data show several strong Cysteine-Cadmium-Cysteine bridges in Shaker potassium channel. PMID: 22538811
6. Synaptic transmission at the larval neuromuscular junction and the transient Shaker potassium current IA in larval muscles have been characterized. PMID: 20429677
7. interaction of the voltage-dependent Shaker potassium channel with the channel-blocking toxin kappa-conotoxin-PVIIA PMID: 11820396
8. Shaker K+ channels contribute to the information capacity of Drosophila photoreceptors PMID: 12571596
9. Second-order kernels of Shaker potassium channel mutants lack a large, early amplification and demonstrate a novel role for Shaker K+ channels in amplifying and accelerating the voltage response of wild-type photoreceptors. PMID: 12761281
10. Results suggest that the external TEA binding site is not within the membrane electric field and that the voltage dependence of TEA block in K+ solutions arises through a coupling with the movement of K+ ions through part of the membrane electric field. PMID: 12885878
11. reduce the metabolic cost of neural information in Drosophila photoreceptors. PMID: 12952637
12. The Shaker voltage-gated potassium channel pore opens when the inner helix bends at a conserved glycine gating hinge. PMID: 15491131
13. Shaker, which encodes a voltage-dependent potassium channel controlling membrane repolarization and transmitter release, may thus regulate sleep need or efficiency; short-sleeping Shaker flies have a reduced lifespan PMID: 15858564
14. observations highlight crucial control of nerve terminal excitability by Shaker & Shab channels to confer temporal patterns of synaptic transmission & suggest participation of these channels in activity-dependent synaptic plasticity PMID: 16763031
15. ShB(delta)K wes activated by binding with toxin 6-bromo-2-mercaptotryptamine (BrMT). PMID: 16801385
16. These results suggest that cooperative insertion of the voltage-sensor transmembrane helices is a property common to K(v) channels and that the degree of cooperativity depends on a balance between electrostatic and hydrophobic forces. PMID: 17488813
17. synaptic strength and synaptic strength at neuromuscular junctions along the dorsal-ventral differentials at physiological Ca(2+) levels were not significantly altered in slowpoke (slo) and Shaker (Sh) mutants PMID: 18539401
18. allosteric communication across disparate regions of the channel protein and between evolved and regulated amino acid changes introduced by RNA editing. PMID: 19114634
