RBMY1E Inhibitors

RBMY1E inhibitors function through a variety of molecular mechanisms, interrupting essential processes that are critical for the proper activity of this RNA-binding protein. Some inhibitors target the splicing factor SF3b complex, directly affecting the splicing of pre-mRNA, a foundational step in RNA maturation, where RBMY1E normally exerts its function. By altering the splicing machinery, these inhibitors may lead to the misprocessing of transcripts that RBMY1E typically regulates, thereby reducing its functional activity. Other compounds take a different approach, focusing on the degradation of specific RNA splicing factors, which could drastically change the RNA splicing landscape and indirectly influence the RNA substrates available to RBMY1E, impeding its role in RNA processing.

Moreover, there are inhibitors that disrupt various signaling pathways, such as those involving tyrosine kinases or the MAPK/ERK cascade, which can have downstream effects on the post-transcriptional modifications and cellular localization of RNA-binding proteins like RBMY1E. This disruption can indirectly lead to a decrease in RBMY1E's functional activity since these signaling pathways may regulate the cellular context in which RBMY1E operates. Additionally, inhibitors that affect cell survival mechanisms or the cell cycle can lead to broader changes in the cellular environment, which could potentially diminish RBMY1E's ability to interact with its RNA targets.
