85-6095-25　Beta-mammal/Insect Toxin Ts1, Recombinant, Tityus serrulatus, aa21-81, His-Tag, Myc-Tag 100ug　583794

特徴

• Voltage-gated sodium channels (Nav) gating-modifier. Acts both as alpha- and beta-toxin, since it affects not only activation but also inactivation of Nav channels (Probable). Binds to Nav domain DII and impairs the four Nav channel voltage sensors movements. Depending on Nav channel subtypes tested, can also bind Nav domains DIII (low affinity) and DIV (very low affinity). Acts on almost all the Nav channels tested (mammalian Nav1.2/SCN2A, Nav1.3/SCN3A, Nav1.4/SCN4A, Nav1.5/SCN5A, Nav1.6/SCN8A, Nav1.9/SCN11A, and insect DmNav1). Is highly active against both mammals and insects. Irreversibly modulates DmNav channels. Other Ts1 activities have been studied, such as immunomodulation, antimicrobial activity or exocrine secretion (Probable). This toxin exhibits an antifungal activity against filamentous fungi. In vitro, it has an important immunomodulatory effect on macrophages by stimulating the release of proinflammatory cytokines. It also shows an activity in exocrine secretion in pancreas, stomach and adrenal gland.
