Chemical activators of MAGE family member C2 influence the protein's activity through various mechanisms. Trichostatin A and 5-Azacytidine can lead to changes in the expression of genes that interact with MAGE family member C2. Trichostatin A, by inhibiting histone deacetylases, causes a more relaxed chromatin structure, which in turn results in increased gene transcription. This can lead to elevated expression of proteins that work in conjunction with MAGE family member C2, enhancing its activity. Similarly, 5-Azacytidine, by inhibiting DNA methyltransferases, causes DNA hypomethylation. This reduction in methylation levels can reactivate silenced genes, potentially increasing the production of proteins that interact with MAGE family member C2, thereby amplifying its functional activity.

Additionally, several proteasome inhibitors, including MG132, Epoxomicin, Bortezomib, Lactacystin, and Z-Leu-Leu-Leu-al, work by preventing the degradation of proteins that regulate the ubiquitin-proteasome system. This system is crucial for protein turnover, and MAGE family member C2 functions within this pathway. By inhibiting proteasomal activity, these chemicals can lead to an accumulation of regulatory proteins, which may stabilize MAGE family member C2 and enhance its functional interactions with other pathway components. Other compounds, such as Withaferin A, Disulfiram, Betulinic acid, Geldanamycin, and Celastrol, activate stress response pathways, which can also impinge upon the activity of MAGE family member C2. For instance, Withaferin A and Betulinic acid induce oxidative stress, which can activate cellular pathways where MAGE family member C2 is involved. Disulfiram forms a complex with copper that inhibits the proteasome, which may lead to the activation of MAGE family member C2 through stabilization of its interacting partners. Geldanamycin, by binding to heat shock protein 90, disrupts the degradation of client proteins that may interact with MAGE family member C2, while Celastrol's mechanism of action is through the inhibition of proteasomal activity, which can similarly lead to an enhancement of MAGE family member C2 activity as part of the stress response.
