Potassium calcium-activated channel subfamily N member 2 (KCNN2) or SK2 is expressed in rat Purkinje cells. The gene encoding this protein is localized on rat chromosome 18q11.
Immunogen
synthetic peptide corresponding to amino acids 542-559 of rat potassium channel SK2.
Application
Anti-Potassium Channel SK2 (Apamin-Sensitive Conductance Ca2+-Dependent K+ Channel, KCa2, Kcnn2, SKCa2) antibody produced in rabbit has been used for immunohistochemistry and immunofluorescence.
Biochem/physiol Actions
Potassium calcium-activated channel subfamily N member 2 (KCNN2) or SK2 has a role in the modulation of intrinsic excitability of neurons and Purkinje cells. It also has a role in synaptic transmission and plasticity. SK2 promotes hippocampus-dependent learning and memory in the mammalian brain.
Physical form
Lyophilized at 0.3-1.4 mg/mL from phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 0.025% - 0.050% sodium azide.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, which is still missing effective therapeutic strategies. Although manipulation of neuronal excitability has been tested in murine and human ALS models, it is still under debate whether neuronal activity might represent
