Activity unknown, even that a lot of targets (Kv, Nav, Cav) have been tested and activities on insects and mice have been tested. Expressed by the venom gland. Has the structural arrangement of an alpha-helix connected to a beta-sheet by disulfide bonds (CS-alpha/beta). Since the toxin contains only 2 disulfide bonds, it is called 2ds-CSalpha/beta. Does not show antimicrobial and ion channel inhbibitory activities. Antimicrobial activity was tested against five bacteria and two fungi, including four Gram-negative bactersoia (E.coli, P.aeruginosa, A.baumannii, and K.pneumoniae), one Gram-positive bacterium (S.aureus), and the fungi C.albicans and C.neoformans (tested at 32 mg/mL). Ion channel inhibitory activity was tested against 16 voltage-gated potassium channels (Kv) (Kv1.1- Kv1.6, Kv2.1, Kv3.1, Kv4.2, Kv7.1-7.2, Kv7.4-7.5, Kv10.1, Kv11.1, and Shaker IR), 9 voltage-gated sodium channels (Nav) (Nav1.1-Nav1.8, BgNav1, and VdNav1), two voltage-gated calcium channels (Cav) (Cav1, Cav2.2), and two nicotinic acetylcholine receptors (nAChR) (alpha-7 nAChR, alpha-3-beta-2/alpha-3-beta-4 nAChR) (tested at 10 uM). In addition, the toxin does not show activity on trigeminal ganglia (500 ug tested) as well as on insects and on mice (absence of flinching or licking). Belongs to the scoloptoxin-15 family. All S.morsitans family members described in 'Undeheim et al., 2014' have not been imported into UniProtKB. Please, refer to this paper to access them.
