TMCO4 Inhibitors
Chemical inhibitors of TMCO4 include a variety of compounds that disrupt different aspects of cellular function, particularly within the endoplasmic reticulum (ER), where TMCO4 is localized. Erastin, for instance, targets the cystine/glutamate antiporter, leading to a decrease in intracellular glutathione levels and subsequent oxidative stress that can alter the redox state of the ER, which is instrumental for the proper function of TMCO4. Similarly, Thapsigargin and Cyclopiazonic acid, both SERCA pump inhibitors, disrupt calcium homeostasis in the ER, which can impair the function of TMCO4 by affecting its folding and maturation within this compartment. Tunicamycin's role in inhibiting N-linked glycosylation can also lead to improper folding and function of TMCO4 if it is subject to this post-translational modification. Brefeldin A further complicates the proper functioning of TMCO4 by disrupting ER to Golgi trafficking, a process that might be necessary for the maturation and function of the protein.
Additional compounds that can impair TMCO4 function include MG-132, which inhibits the proteasome, leading to an accumulation of misfolded proteins in the ER and subsequent ER stress which can affect the folding and function of TMCO4. Salubrinal and Sephin1, which modulate the phosphorylation state of eIF2α, can also indirectly inhibit TMCO4 by altering protein synthesis rates during stress conditions, affecting the overall protein homeostasis within the ER. Eeyarestatin I's inhibition of ER-associated degradation (ERAD) can result in the accumulation of misfolded TMCO4, while Ceapin-A7 and GSK2606414, inhibitors of ATF6 and PERK signaling respectively, can impact the unfolded protein response (UPR), thereby potentially affecting TMCO4 function. Lastly, 4-Phenylbutyric acid acts as a chemical chaperone, influencing ER stress and protein folding environments, which in turn can impact the function of TMCO4 within the ER.

Erastin | 571203-78-6 | sc-205677 sc-205677A | 5 mg 50 mg | $372.00 $1614.00 | 1 | |
Erastin targets the cystine/glutamate antiporter system xc-, leading to depletion of intracellular glutathione. This reduction in glutathione can potentiate oxidative stress, which may indirectly inhibit TMCO4 by altering the redox state of the ER where TMCO4 is localized, affecting its function. | ||||||
Thapsigargin | 67526-95-8 | sc-24017 sc-24017A | 1 mg 5 mg | $136.00 $446.00 | 114 | |
Thapsigargin is a SERCA pump inhibitor that disrupts calcium homeostasis in the endoplasmic reticulum (ER). As TMCO4 is an ER resident protein, dysregulation of ER calcium can impair proper folding and function of TMCO4 by perturbing its ER environment. | ||||||
Tunicamycin | 11089-65-9 | sc-3506A sc-3506 | 5 mg 10 mg | $172.00 $305.00 | 66 | |
Tunicamycin inhibits N-linked glycosylation in the ER. If TMCO4 undergoes glycosylation, tunicamycin could impede its proper folding and function by preventing this post-translational modification. | ||||||
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 disrupts ER to Golgi trafficking. If TMCO4 requires Golgi processing for its function, this agent would inhibit TMCO4 by blocking its trafficking and subsequent functional maturation. | ||||||
Cyclopiazonic Acid | 18172-33-3 | sc-201510 sc-201510A | 10 mg 50 mg | $176.00 $624.00 | 3 | |
Cyclopiazonic acid is another SERCA pump inhibitor, leading to disturbances in ER calcium homeostasis. Similar to thapsigargin, this disruption can indirectly inhibit TMCO4 by affecting its ER environment, which is crucial for its proper function. | ||||||
MG-132 [Z-Leu- Leu-Leu-CHO] | 133407-82-6 | sc-201270 sc-201270A sc-201270B | 5 mg 25 mg 100 mg | $60.00 $265.00 $1000.00 | 163 | |
MG-132 is a proteasome inhibitor that can lead to the accumulation of misfolded or damaged proteins within the ER, causing ER stress. ER stress can indirectly inhibit TMCO4 by impairing the overall protein processing capacity of the ER, potentially affecting TMCO4 folding and function. | ||||||
Salubrinal | 405060-95-9 | sc-202332 sc-202332A | 1 mg 5 mg | $34.00 $104.00 | 87 | |
Salubrinal is a selective inhibitor of eIF2α dephosphorylation, which leads to reduced global protein synthesis. This can indirectly inhibit TMCO4 by limiting its synthesis during times of ER stress, aiming to restore ER homeostasis. | ||||||
Eeyarestatin I | 412960-54-4 | sc-358130B sc-358130 sc-358130A sc-358130C sc-358130D sc-358130E | 5 mg 10 mg 25 mg 50 mg 100 mg 500 mg | $114.00 $203.00 $354.00 $697.00 $1363.00 $5836.00 | 12 | |
Eeyarestatin I inhibits ER-associated degradation (ERAD). If TMCO4 is subject to ERAD, inhibition of this pathway can lead to its accumulation in its misfolded state, indirectly inhibiting its function. | ||||||
GSK 2606414 | 1337531-36-8 | sc-490182 sc-490182A | 5 mg 25 mg | $163.00 $572.00 | ||
GSK2606414 is a potent inhibitor of PERK, one of the ER stress sensors. Inhibition of PERK signaling could indirectly inhibit TMCO4 by affecting the UPR pathway and ER homeostasis, which is essential for TMCO4's function. | ||||||
