γ2-Adaptin Inhibitors
Chemical inhibitors of γ2-Adaptin can impact its function through various mechanisms that interfere with the intracellular vesicular trafficking pathways. Brefeldin A, for instance, disrupts the function of γ2-Adaptin by inhibiting the ARF GTPase, leading to the collapse of the Golgi structure and subsequent misdirection of vesicle transport. Dynasore and MiTMAB, which are inhibitors of the GTPase dynamin, prevent the scission of clathrin-coated vesicles from the plasma membrane, thereby impeding the function of γ2-Adaptin in vesicle formation and release. Similarly, Pitstop 2 and Ikarugamycin obstruct the formation of clathrin-coated vesicles by blocking the interaction between clathrin and adaptor proteins, such as the AP-1 complex, where γ2-Adaptin is a critical component. This blockage leads to an inability for γ2-Adaptin to perform its role in sorting and incorporating cargo into forming vesicles.
Chlorpromazine further contributes to the inhibition of γ2-Adaptin by preventing the assembly of clathrin with adaptor proteins, thus stalling the formation of vesicles in which γ2-Adaptin is involved. In a different aspect of vesicle trafficking, ML141 inhibits the GTPase Cdc42, leading to disruption in actin cytoskeleton dynamics, which are crucial for the movement and secretion of vesicles, indirectly affecting the function of γ2-Adaptin. Tyrphostin A23 inhibits tyrosine kinases that are responsible for the phosphorylation of proteins involved in clathrin-mediated endocytosis, which can affect the regulation of γ2-Adaptin's role in vesicle formation. Monodansylcadaverine, by inhibiting transglutaminase, disrupts the stability and trafficking of vesicles, which can alter the function of γ2-Adaptin as it is involved in vesicle formation through the AP-1 complex. Collectively, these inhibitors can lead to a broad disruption of γ2-Adaptin's role in vesicular trafficking by targeting different proteins and processes within the endocytic pathway.

Brefeldin A | 20350-15-6 | sc-200861C sc-200861 sc-200861A sc-200861B | 1 mg 5 mg 25 mg 100 mg | $31.00 $53.00 $124.00 $374.00 | 25 | |
Brefeldin A inhibits ADP-ribosylation factor (ARF), a small GTPase involved in vesicle formation and transport between the Golgi and the endoplasmic reticulum. γ2-Adaptin, a component of the AP-1 adaptor complex, is dependent on ARF for the formation of clathrin-coated vesicles. Inhibition of ARF by Brefeldin A disrupts the formation of these vesicles, thereby functionally inhibiting γ2-Adaptin by preventing its role in vesicular trafficking. | ||||||
Dynamin Inhibitor I, Dynasore | 304448-55-3 | sc-202592 | 10 mg | $89.00 | 44 | |
Dynasore is a GTPase inhibitor that targets dynamin, which is crucial for the scission of clathrin-coated vesicles from membranes. Since γ2-Adaptin is involved in the formation of clathrin-coated vesicles, the inhibition of dynamin by Dynasore would disrupt vesicle scission and trafficking, leading to a functional inhibition of γ2-Adaptin as it cannot complete the vesicle formation process. | ||||||
Pitstop 2 | 1419320-73-2 | sc-507418 | 10 mg | $360.00 | ||
Pitstop 2 is a selective clathrin inhibitor. It blocks the interaction between clathrin and adaptor proteins, including the AP-1 complex, which contains γ2-Adaptin. The inhibition of clathrin function by Pitstop 2 prevents the formation of clathrin-coated vesicles, thereby inhibiting the function of γ2-Adaptin as it cannot participate in vesicle formation and cargo selection. | ||||||
Chlorpromazine | 50-53-3 | sc-357313 sc-357313A | 5 g 25 g | $61.00 $110.00 | 21 | |
Chlorpromazine is known to disrupt clathrin-mediated endocytosis by preventing the assembly of clathrin and adaptor proteins such as AP-1, which includes γ2-Adaptin. This disruption leads to functional inhibition of γ2-Adaptin as it cannot aid in the formation of clathrin-coated vesicles, impairing the endocytosis process. | ||||||

ML141 is a potent inhibitor of Cdc42, a member of the Rho family GTPases. Cdc42 plays a role in actin polymerization and vesicle trafficking. By inhibiting Cdc42, ML141 can disrupt the actin cytoskeleton dynamics and membrane trafficking events that are essential for the function of γ2-Adaptin in vesicle formation and movement. | ||||||
Ikarugamycin | 36531-78-9 | sc-202179 | 500 µg | $189.00 | 4 | |
Ikarugamycin inhibits clathrin-mediated endocytosis by interfering with the interaction between clathrin and adaptor protein complexes, including the AP-1 complex containing γ2-Adaptin. This interference blocks the formation of clathrin-coated pits and vesicles, leading to functional inhibition of γ2-Adaptin. | ||||||

Tyrphostin A23 is an inhibitor of tyrosine kinases and has been shown to interfere with endocytosis. It can inhibit the phosphorylation of proteins involved in clathrin-mediated endocytosis, impacting the function of adaptor protein complexes such as AP-1, which includes γ2-Adaptin. | ||||||

Monodansylcadaverine is an inhibitor of transglutaminase and has been shown to block endocytosis. It can non-specifically interfere with vesicle formation by inhibiting the crosslinking of proteins on vesicles. As γ2-Adaptin is involved in vesicle formation through the AP-1 complex, its function is inhibited by monodansylcadaverine through the disruption of vesicle stability and trafficking. | ||||||
