Application

Adenosine 5′-[γ-thio]triphosphate tetralithium salt has been used to treat the pollen grains to determine the inhibitory effect of adenosine triphosphate (ATP) or its hydrolysis product. It has also been used to select thiophosphorylate target protein.

Biochem/physiol Actions

Adenosine 5′-[γ-thio]triphosphate (ATP-γ-S) is widely used as a non-hydrolyzed ATP analogue for studies on the effects of ATP binding to ATP sites in a wide range of processes including extracellular functions. ATP- γ-S is a P2 purinergic agonist which increases the activity of Ca2+-activated K+ channels. ATP- γ-S can substitute for ATP in kinase reactions yielding thiophosphorylated proteins that are resistant to protein phosphatases and modulate the ATP-dependent steps in the binding of ubiquitin conjugates to the 26S proteasome. ATP-γ -S differentially modulates Toll-like receptor 4-mediated cell survival and death.
