    Function

    TJP1, TJP2, and TJP3 are closely related scaffolding proteins that link tight junction (TJ) transmembrane proteins such as claudins, junctional adhesion molecules, and occludin to the actin cytoskeleton (PubMed:16129888). The tight junction acts to limit movement of substances through the paracellular space and as a boundary between the compositionally distinct apical and basolateral plasma membrane domains of epithelial and endothelial cells. Binds and recruits PATJ to tight junctions where it connects and stabilizes apical and lateral components of tight junctions (PubMed:16129888). Promotes cell-cycle progression through the sequestration of cyclin D1 (CCND1) at tight junctions during mitosis which prevents CCND1 degradation during M-phase and enables S-phase transition (PubMed:21411630). With TJP1 and TJP2, participates in the junctional retention and stability of the transcription factor DBPA, but is not involved in its shuttling to the nucleus (By similarity). Contrary to TJP2, TJP3 is dispensable for individual viability, embryonic development, epithelial differentiation, and the establishment of TJs, at least in the laboratory environment (By similarity).

    Notes

    ab250601 is the carrier-free version of Anti-Zonula occludens protein 3/ZO3 antibody [EPR13414-152] ab182159.

    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • - High batch-to-batch consistency and reproducibility
    • - Improved sensitivity and specificity
    • - Long-term security of supply
    • - Animal-free batch production

    For more information, read more on recombinant antibodies.

    Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

    This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

    Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

    This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

    Activity summary

    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.

    Associated diseases and disorders

    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.
