Binds specifically to type 1 RyR (RyR1) from skeletal muscle. Inhibit both the binding of ryanodine to RyR1, and RyR1's calcium-channel activity. Inhibits carbachol-induced muscle contraction and weakly blocks muscle contraction evoked by potassium.<ref>PMID:15581679</ref> <ref>PMID:17070778</ref> <ref>PMID:18658224</ref> <ref>PMID:16042391</ref> |
