Text mining Term SK2
UniProt ID KCNN2_RAT
Name Small conductance calcium-activated potassium channel protein 2
SK2
SKCa 2
KCa2.2
SKCa2
Gene Names Kcnn2
Taxonomy Rattus norvegicus

General annotation

Function 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.
Subcellular location Membrane; Multi-pass membrane protein.
