Biological function summary

Occludin serves as an important component in maintaining cell-to-cell adhesion within tight junction complexes. It interacts with other tight junction proteins such as claudins and junctional adhesion molecules to regulate paracellular permeability. These interactions help maintain selective barrier properties of epithelial and endothelial layers preventing the passage of large molecules and pathogens while allowing passage of ions and small molecules. Occludin stabilizes the tight junctions by interacting with the cytoskeleton and signaling proteins that are important for tight junction assembly and maintenance.

Pathways

Occludin functions prominently in the regulation of tight junction integrity and barrier function. It participates in pathways such as the tight junction signaling pathway and the paracellular transport pathway. Occludin interacts with ZO-1 a scaffolding protein bridging its interaction with the actin cytoskeleton which supports the structural organization and function of tight junctions. This connectivity allows for regulation of the permeability and transport across the epithelial barrier.
