Gene: Kcnn2 (potassium calcium-activated channel subfamily N member 2) Rattus norvegicus
Symbol: Kcnn2
Name: potassium calcium-activated channel subfamily N member 2
RGD ID: 2963
Description: Exhibits calmodulin binding activity and small conductance calcium-activated potassium channel activity. Involved in potassium ion transport and regulation of neuronal synaptic plasticity. Localizes to dendritic spine; integral component of membrane; and neuronal cell body. Orthologous to human KCNN2 (potassium calcium-activated channel subfamily N member 2); PARTICIPATES IN calcium/calcium-mediated signaling pathway; bile acid transport pathway; INTERACTS WITH (+)-pilocarpine; 2,3,7,8-tetrachlorodibenzodioxine; acetamide.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: KCa2.2; potassium channel, calcium activated intermediate/small conductance subfamily N alpha, member 2; potassium intermediate/small conductance calcium-activated channel, subfamily N, member 2; SK2; SKCa 2; SKCa2; small conductance calcium-activated channel, subfamily N, member 2; small conductance calcium-activated potassium channel protein 2
