TLDR Folliculin deficiency causes problems with cell division and positioning due to disrupted RhoA signaling and interaction with p0071.

The study investigated the interaction between folliculin (FLCN) and p0071 (plakophilin-4), revealing that FLCN deficiency disrupted RhoA signaling, epithelial polarization, and cytokinesis. This disruption led to increased cell migration, tight junction defects, and mislocalization of junctional proteins like E-cadherin. The findings highlighted the crucial role of the FLCN/p0071 complex in maintaining cell structure and function, suggesting potential therapeutic targets for diseases related to FLCN deficiency, such as Birt–Hogg–Dubé syndrome.
