Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.02Å Ligands: CA, SO4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function KCNN2_RAT Forms a voltage-independent potassium channel activated by intracellular calcium. Activation is followed by membrane hyperpolarization. Thought to regulate neuronal excitability by contributing to the slow component of synaptic afterhyperpolarization. The channel is blocked by apamin. See Also Calmodulin 3D structures Potassium channel 3D structures
