PARD6B Inhibitors

PARD6B inhibitors belong to a distinct class of chemical compounds designed to modulate the activity of the protein Par-6 family cell polarity regulator beta (PARD6B). PARD6B is a critical component of the Par complex, a protein assembly involved in the establishment and maintenance of cell polarity in various tissues and cell types. Cell polarity is essential for a wide range of biological processes, including cell migration, tissue development, and organogenesis. PARD6B inhibitors are specifically designed to interfere with the function of PARD6B, which in turn affects the organization of cellular structures and cell-cell interactions.

The mechanism of action of PARD6B inhibitors primarily involves targeting the PARD6B protein itself or its associated protein-protein interactions. These inhibitors can disrupt the binding of PARD6B to its partner proteins, such as aPKC (atypical protein kinase C), Par-3, and Par-1, thereby perturbing the overall Par complex and, consequently, cell polarity. By doing so, PARD6B inhibitors offer researchers valuable tools to investigate the fundamental cellular processes that rely on proper cell polarity establishment, such as embryonic development, tissue homeostasis, and wound healing. Additionally, the study of PARD6B inhibitors may shed light on avenues in the future, given the crucial role of cell polarity in various disease states, including cancer metastasis and tissue regeneration.
