| + | [https://www.uniprot.org/uniprot/KAX54_HOTTA KAX54_HOTTA] Blocks small conductance calcium-activated potassium channels (PubMed:12239213). Shows activity on KCa2.2/KCNN2 (IC(50)=0.0243 nM), KCa2.3/KCNN3 (IC(50)=1.7 nM), and KCa2.1/KCNN1 (IC(50)=42 nM) (PubMed:12239213). Induces cell death when tested on Jurkat E6-1 and human mammary breast cancer MDA-MB-231 which constituvely express KCa2.2/KCNN2, but not on human peripheral blood lymphocytes (which do not express KCa2.2/KCNN2) (PubMed:24821061).<ref>PMID:12239213</ref> | ||
