==About this Structure==
</table>
[[1sco]] is a 1 chain structure with sequence from [http://en.wikipedia.org/wiki/Orthochirus_scrobiculosus Orthochirus scrobiculosus]. Full experimental information is available from [http://oca.weizmann.ac.il/oca-bin/ocashort?id=1SCO OCA].  
== Function ==
[https://www.uniprot.org/uniprot/KAX37_ORTSC KAX37_ORTSC] Blocks voltage-gated potassium channels Kv1.1/KCNA1 (IC(50)=0.6nM), Kv1.2/KCNA2 (IC(50)=5.4nM), Kv1.3/KCNA3 (IC(50)=0.014nM) potently, and moderately block intermediate conductance calcium-activated potassium channels KCa3.1/KCNN4 (IC(50)=225nM). At high concentration (2 mM), is also active on Kv1.6/KCNA6 and Shaker IR.[REFERENCE:1]<ref>PMID:15588251</ref>
