IFT140 Inhibitors

IFT140, belonging to the intraflagellar transport (IFT) complex, plays a pivotal role in the intricate processes that drive the formation, maintenance, and signaling dynamics of primary cilia. As a subunit of the IFT complex A, IFT140's contributions are integral to the proper operation of these hair-like organelles found on the cell surface, known as primary cilia. This complex apparatus acts as a sensory structure for cells, receiving various external signals and translating them for cellular comprehension. Given the significance of primary cilia in myriad cellular operations, disruptions or aberrations in the functionality of IFT140 can lead to a cascade of cellular dysregulations, underpinning the importance of understanding and modulating its activity.

IFT140 inhibitors, as a conceptual class, target the mechanisms associated with intraflagellar transport. These inhibitors can act by impeding the ATPase activity crucial for the proper movement within the cilia or by affecting ciliary-associated signaling pathways. This is not to say that they target IFT140 directly; instead, their mechanism of action often revolves around modulating the broader cellular environment in which IFT140 operates, thus indirectly influencing its activity. By affecting the associated pathways and processes, these inhibitors can alter the dynamics of ciliary assembly, maintenance, or signaling. The overall objective of this class is to intervene in the IFT process, either slowing it down, halting it, or modifying its trajectory, thereby indirectly impacting IFT140's role and function within the cell. While the specifics of each inhibitor's action vary, their shared goal is the modulation of intraflagellar transport and, by extension, the function of primary cilia.
