- Structural and functional properties of ryanodine receptor type 3 in zebrafish tail muscle
RyR3 is the major component of parajunctional feet in skeletal muscle and the main ryanodine receptor mediating Ca2+ sparks.
- Positions of the cytoplasmic end of BK α S0 helix relative to S1–S6 and of β1 TM1 and TM2 relative to S0–S6
The BK β1 subunit displaces the unique S0 transmembrane helix on the intracellular side of BK α but not on the extracellular side, thereby altering its path through the membrane.
- Identification of a key residue in Kv7.1 potassium channel essential for sensing external potassium ions
A glutamate at position 290 in the human Kv7.1 S5-pore linker is required for its inhibition by high concentrations of extracellular potassium.
- Rhodopsin kinase and recoverin modulate phosphodiesterase during mouse photoreceptor light adaptation
Rhodopsin kinase and its calcium-dependent inhibitor recoverin regulate decay of light-activated phosphodiesterase activity, enabling rods to respond rapidly to changes in light intensity in the presence of background light.
