Biological function summary
This claudin protein contributes to establishing and maintaining the barrier function that controls paracellular transport which is the movement of substances between cells. Claudin 1 participates as a critical component of the tight junction complex and it interacts with other proteins such as occludin and zonula occludens. These interactions contribute to the regulation and maintenance of cell polarity and signaling.
Pathways
Claudin 1 is involved in the epithelial cell signaling pathways that influence cellular proliferation and differentiation. One significant pathway is the Wnt signaling pathway where claudin 1 cooperates with other claudins and proteins like Β-catenin to regulate gene transcription. Additionally it is implicated in the MAPK pathway which involves signaling cascades that affect cell growth division and response to external stress.
