INTS3 Activators

INTS3 Activators would comprise a class of chemicals that modulate the activity of Integrator complex subunit 3 indirectly by influencing cellular mechanisms that regulate the expression or stability of the protein. The transcription and subsequent synthesis of the INTS3 protein can be upregulated through the action of chemicals that modify the chromatin state, such as 5-Azacytidine and histone deacetylase inhibitors like Trichostatin A, SAHA, and Sodium Butyrate. These compounds can activate INTS3 by reducing DNA methylation levels or increasing histone acetylation at the INTS3 gene locus, which loosens chromatin structure and promotes transcription factor access. Hormone-like signals, including retinoic acid and beta-estradiol, exert their effects by interacting with their respective receptors, which bind to the INTS3 gene's regulatory regions, enhancing its expression.

On the other hand, stabilization of the INTS3 protein and prevention of its degradation also serve as activation mechanisms. Compounds like Disulfiram and MG132 block the proteasomal degradation pathway, while Chloroquine disrupts lysosomal degradation through autophagy inhibition, leading to an accumulation of the INTS3 protein within the cell. Lithium Chloride and Rapamycin act on upstream kinases like GSK-3 and signaling pathways like mTOR, respectively, which can modify the turnover and synthesis of INTS3.
