fibrocystin

Fibrocystin is a protein encoded by the PKHD1 gene. It is primarily found in the primary cilia of kidney and liver cells. The protein is believed to play a role in regulating the development and function of these organs, particularly in the formation of bile ducts and nephrons. Mutations in the PKHD1 gene, which lead to dysfunctional fibrocystin, are the cause of autosomal recessive polycystic kidney disease (ARPKD). ARPKD is a genetic disorder characterized by the development of numerous cysts in the kidneys and liver, leading to impaired organ function. Research suggests fibrocystin interacts with other proteins involved in cell signaling and structural organization, contributing to the maintenance of healthy kidney and liver tissues. The exact mechanisms by which fibrocystin functions and how its dysfunction leads to cyst formation are still areas of active investigation. Understanding fibrocystin's role is crucial for developing potential therapeutic strategies for ARPKD.
