Comments Information
Function
- Exhibits unusual shark repellent and surfactant properties. Forms voltage-dependent, ion-permeable channels in membranes. At high concentration causes cell membrane lysis.
Subunit structure
- In aqueous solution exists as a tetramer.
Domain
- Consists of a C-terminal hydrophilic region and a predominantly hydrophobic remainder.
