功能：

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.

1. SK2 channels regulate mitochondrial respiration and mitochondrial Ca(2+) uptake. PMID: 28282037
2. Probing the responsible cellular mechanisms pinpoints a disturbance in the expression and function of small-conductance Ca(2+)-activated K(+) (SK) channels and reveals an important role for both SK2 and SK3 channels in normal regulation of serotinin (5-HT) neuronal excitability. PMID: 27874831
3. SK2 is nuclear in primary neurons and, unexpectedly, overexpressed SK2 is neurotoxic in a dose-dependent manner..

4. Thus, MPP2 is a novel synaptic scaffold that is required for proper synaptic localization and function of SK2-containing channels. PMID: 26880549
5. In addition to a well-established role for KCa2.x channels in migration, blockade of these channels was potently cytotoxic in breast cancer cell lines. PMID: 26454020
6. Atrial SK2 and SK3 are significantly down-regulated from accelerated turnover in diabetic mice, resulting in action potential prolongation and arrhythmias. PMID: 25605734

16. Results indicate that SK2-L directs synaptic SK2-containing channel expression and is important for normal synaptic signaling, plasticity and learning. PMID: 21602822
17. Thus, SK2-sh as a downstream target of cytokines, provide a promising target for additional investigation regarding potential therapeutic intervention.(SH2-SH PROTEIN, MOUSE) PMID: 18624921
18. Under basal conditions SK2 channels do not undergo rapid recycling and are present within the spine in a population of endosomes distinct from alpha-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate receptors (AMPARs). PMID: 20810893
19. Because of the marked differential expression of SK2 channels in the heart, specific ligands for Ca2+-activated K+ currents may offer a unique therapeutic opportunity to modify atrial cells without interfering with ventricular myocytes PMID: 13679367

21. At the cellular level, SK2-like immunoreactivity is primarily localized to somatic and dendritic structures in mouse brain. PMID: 15234350
