Potassium voltage-gated channel protein Shal; Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient. May play a role in the nervous system and in the regulation of beating frequency in pacemaker cells.

Potassium voltage-gated channel protein Shab; Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.

Hyperkinetic, isoform M; Hyperkinetic (Hk) encodes a beta-subunit of Sh K[+] channels and modulates its channel function. It is important in regulating action potentials in neurons and muscles, and transmitter release.

KCNQ potassium channel, isoform F; KCNQ potassium channel (KCNQ) encodes a voltage-gated channel involved in cardiac muscle contraction; Belongs to the potassium channel family.

Calmodulin; Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+) (By similarity). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases (By similarity). In photoreceptor cells, light-induced Ca(2+) influx activates calmodulin, which in turn is likely to promote Crag activity in trafficking of newly synthesized ninaE (Rh1) from the trans-Golgi network to rhabdomere membranes. Together with Akap200, regulates PKA activity and ethanol-induced sensitivity and tolerance.

Potassium voltage-gated channel protein Shaker; 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 ; Belongs to the potassium channel family. A (Shaker) (TC 1.A.1.2) s [...]

Calcium-activated potassium channel slowpoke; Potassium channel activated by both membrane depolarization or increase in cytosolic Ca(2+) that mediates export of K(+). Its activation dampens the excitatory events that elevate the cytosolic Ca(2+) concentration and/or depolarize the cell membrane. It therefore contributes to repolarization of the membrane potential. Kinetics are determined by alternative splicing, phosphorylation status and its combination interaction with Slob and 14-3-3-zeta. While the interaction with Slob1 alone increases its activity, its interaction with both Slob [...]

Shaw-like, isoform C; Delayed rectifier potassium channel activity; voltage-gated potassium channel activity; voltage-gated cation channel activity. It is involved in the biological process described with: potassium ion transmembrane transport; potassium ion transport; protein homooligomerization.

Calcium-binding protein E63-1; Ecdysone-induced protein 63F 1 (Eip63F-1) encodes a member of the EF-hand family of Ca[2+]-binding proteins, induced directly by 20-hydroxyecdysone in late third instar larvae. It is responsible for formation of the 63F early puff in the polytene chromosomes.
