Short Name | Troponin_sf |
description | The troponin (Tn) complex regulates Ca2+induced muscle contraction. Tn contains three subunits, Ca2+binding (TnC), inhibitory (TnI), and tropomyosin binding (TnT). This entry includes domains from troponin T and troponin I. Troponin I binds to actin and troponin T binds to tropomyosin [, , ]. Structurally this domain forms a heterodimeric coiled coil. |
