Zonula occludens protein 3 (ZO-3) also known as Tight junction protein 3 is a component of tight junction complexes located in epithelial and endothelial cells. ZO-3 exhibits a molecular mass of approximately 130 kDa. Within the cellular environment ZO-3 serves as a scaffold protein anchoring transmembrane proteins to the actin cytoskeleton maintaining tight junction integrity. Expressions of ZO-3 occur in tissues where tight junctions are present including the intestinal epithelium and blood-brain barrier.
Biological function summary
ZO-3 participates with other proteins in maintaining cellular polarity and regulating paracellular permeability. It forms a part of the tight junction complex where it interacts with proteins like ZO-1 and occludin. Through these interactions ZO-3 contributes to the junctional barrier between adjacent cells playing an essential role in controlling the passage of molecules and ions through these cellular layers. ZO-3 also helps in signal transduction pathways linked to cellular proliferation and differentiation.
Pathways
ZO-3 plays a significant role in tight junction signaling and the establishment of epithelial cell adhesion. Within these pathways ZO-3 collaborates with ZO-1 and other junctional proteins forming a network that regulates cellular responses to extracellular stimuli. These associations reinforce the epithelial barrier and help manage processes such as inflammation and tissue repair important for maintaining tissue homeostasis.
Zonula occludens protein 3 has a connection to conditions like inflammatory bowel disease (IBD) and certain cancers. Variations or disruptions in ZO-3 expression can weaken the intestinal barrier having potentially contributing effects on the development of IBD. Furthermore ZO-3 has an association with tumor suppressor proteins like ZO-1 suggesting that its dysfunction might play a role in the progression of cancerous growths by altering barrier properties and influencing cell proliferation.
