Homologous Superfamily

Troponin domain superfamily (IPR038077)

Short name: Troponin_sf

Overlapping entries


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 [PMID: 3102969, PMID: 7852318, PMID: 7601340]. Structurally this domain forms a heterodimeric coiled coil.
