Targets

General Function:
Protein kinase binding
Specific Function:
Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.
Gene Name:
ACTA2
Uniprot ID:
P62736
Molecular Weight:
42008.57 Da
Mechanism of Action:
Phallotoxins bind actin, preventing its depolymerization and poisoning the cell. They bind specifically at the interface between F-actin subunits, locking adjacent subunits together. This leads to a decrease in the rate constant for the dissociation of actin subunits from filament ends, which essentially stabilizes actin filaments through the prevention of filament depolymerization. Moreover, they inhibit the ATP hydrolysis activity of F-actin.
