α-mapi

MAPI is an irreversible peptidyl 3C cysteine protease (SV3CP) inhibitor. By covalently attaching its C-terminal Michael acceptor moiety to the active site thiol of SV3CP Cys 139, MAPI inhibits SV3CP. It shows potential for use in the study of norovirus infections.

Tamapin, a venom peptide isolated from the Indian red scorpion (Mesobuthus tamulus) [1], selectively targets and blocks small-conductance Ca(2+)-activated K(+) (SK) channels, particularily SK2 (Potassium Channel). It inhibits SK channel-mediated currents in the pyramidal neurons of the hippocampus.

Tamapin TFA, a venom peptide isolated from the Indian red scorpion (Mesobuthus tamulus) [1], selectively targets and blocks small conductance Ca(2+)-activated K(+) (SK) channels, particularly the SK2 subtype (Potassium Channel). It is known to inhibit SK channel-mediated currents in the hippocampal pyramidal neurons.
