SOLUTION STRUCTURE OF NEUROTOXIN I FROM THE SEA ANEMONE STICHODACTYLA HELIANTHUS. A NUCLEAR MAGNETIC RESONANCE, DISTANCE GEOMETRY AND RESTRAINED MOLECULAR DYNAMICS STUDY
1sh1 is a 1 chain structure with sequence from Stichodactyla helianthus. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
NA21_STIHL Binds specifically to voltage-gated sodium channels (Nav), thereby delaying their inactivation during signal transduction (By similarity). Is highly toxic to crabs (by intrahemocoelic injection) (PubMed:2568126, PubMed:22015268), but without effect upon mice (by intraperitoneal injection) (PubMed:2568126).[1][2]
