IFT80 Inhibitors

IFT80 inhibitors belong to a specialized class of chemical compounds designed to target and modulate the activity of IFT80, a protein that plays a pivotal role in the process of intraflagellar transport (IFT). IFT is a fundamental cellular mechanism that operates in eukaryotic organisms, including humans, and is essential for the assembly and maintenance of cilia and flagella. These hair-like structures protrude from the surface of many cell types and have diverse functions, including cellular motility and sensory perception. IFT80 is part of the IFT complex B, one of two multiprotein complexes (complex A and complex B) that transport cargo, including structural and signaling proteins, along the microtubule-based axoneme within cilia and flagella.

Structurally, IFT80 inhibitors are carefully designed to interact with specific regions or binding sites on the IFT80 protein, disrupting its normal functioning within the IFT complex B. By interfering with IFT80's role as a component of the transport machinery, these inhibitors affect the trafficking of essential proteins within cilia and flagella. As a result, the assembly and maintenance of these organelles may be compromised, leading to defects in cellular motility and sensory functions. Research on IFT80 inhibitors is critical for gaining insights into the complex processes underlying cilia and flagella biology, as well as their roles in various physiological and developmental processes in multicellular organisms. Additionally, these inhibitors serve as valuable tools for studying the intricate mechanisms of intraflagellar transport, contributing to a deeper understanding of fundamental cellular biology.
