Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Occludin antibody (AB235986)

Paraffin-embedded human colon cancer tissue stained for Occludin using ab235986 at 1/400 dilution in immunohistochemical analysis.

After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30 minutes at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized tissue using an HRP conjugated SP system.

Occludin is a protein that plays an important mechanical role in forming tight junctions which are specialized connections between neighboring cell membranes. Alternative names for this target include occludin-1. The occludin protein has a molecular weight of approximately 65 kDa. It is expressed in a variety of tissues but levels tend to be high in epithelial and endothelial cells where tight junctions are essential for barrier functions. Occludin acts as integral membrane protein contributing to the complex structures that seal spaces between cells.
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.

Disruptions in occludin function are connected to conditions such as inflammatory bowel disease (IBD) and some cancers. In IBD abnormal occludin expression can compromise intestinal barrier function leading to increased intestinal permeability and an inflammatory response. In certain cancers loss of occludin expression is linked to increased invasiveness and metastasis due to weakened cell adhesion. The dysfunction of proteins like ZO-1 which interact with occludin in these pathways also contributes to these pathological states highlighting the importance of occludin's regulatory roles in maintaining cellular barrier integrity.
