1. Membrane Transporter/Ion Channel
  2. Sodium Channel
  3. MitTx-alpha

MitTx-alpha is a subunit of MitTx. MitTx is a potent, persistent, and selective agonist for acid-sensing ion channels (ASICs). MitTx is highly selective for the ASIC1 subtype at neutral pH; under more acidic conditions (pH<6.5), MitTx massively potentiates (>100-fold) proton-evoked activation of ASIC2a channels.

Description

MitTx-alpha is a subunit of MitTx. MitTx is a potent, persistent, and selective agonist for acid-sensing ion channels (ASICs). MitTx is highly selective for the ASIC1 subtype at neutral pH; under more acidic conditions (pH<6.5), MitTx massively potentiates (>100-fold) proton-evoked activation of ASIC2a channels[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
