UniProtKB accession:  P59936

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Potently blocks Kv1.3/KCNA3, Kv1.2/KCNA2, and Shaker potassium channels (PubMed:24590385) and inhibits high conductance calcium-activated potassium channels (PubMed:10082164). Is potent against Kv1.3/KCNN3 (IC(50)=0.55 nM) and Kv1.2/KCNN2 (IC(50)=6.19 nM) (PubMed:24590385). It also stimulates the release of NO, IL-6 and TNF-alpha in J774.1 cells and presents a pro-inflammatory activity in mice (PubMed:21549737, PubMed:23085190).
