| - | + | [https://www.uniprot.org/uniprot/MTX4_GRARO MTX4_GRARO] This cationic hydrophobic peptide inhibits a lot of different channels and has an antimicrobial activity. It blocks mechanosensitive ion channels (also named stretch-activated channels or SACs), without having effect on whole-cell voltage-sensitive currents. Acts by partitioning into the membrane and perturbing the interface between the channel and the lipid bilayer without necessarily being in physical contact with the channel. Inhibits atrial fibrillation as well as the membrane motor of outer hair cells at low doses. It also binds to the voltage sensor of voltage-gated potassium channels from the archaebacterium Aeropyrum pernix (KvAP) without affecting channel gating. It has also a medium toxicity on a large spectra of sodium channels (Nav1.1/SCN1A, Nav1.2/SCN2A, Nav1.3/SCN3A, Nav1.4/SCN4A, Nav1.5/SCN5A, Nav1.6/SCN8A, Nav1.7/SCN9A), and also inhibits potassium channels Kv11.1/KCNH2 and Kv11.2/KCNH6. It also exhibits antimicrobial activities against the Gram-positive bacteria B.subtilis (MIC=0.5 uM), S.aureus (MIC=2-4 uM), and S.epidermidis (MIC=4-8 uM), and Gram-negative bacteria S.typhimurium (MIC=32.64 uM), P.aeruginosa (MIC=8-16 uM), and E.coli (MIC=8-16 uM).<ref>PMID:10779316</ref> <ref>PMID:11343101</ref> <ref>PMID:15241420</ref> <ref>PMID:15287735</ref> <ref>PMID:16376854</ref> <ref>PMID:16797839</ref> <ref>PMID:17384064</ref> <ref>PMID:17573432</ref> <ref>PMID:19955179</ref> | |
