Hintergrundinformationen
What is the function of ZO-1?
Zona Occludens 1 (ZO-1) is a tight junction (TJ) protein found in complexes at cell-cell contacts. The role of ZO-1 is to recruit other TJ proteins.1,2 The resulting TJ complexes regulate paracellular flow, contribute to apical-basal polarity, and are part of signaling pathways for proliferation and differentiation.3 This protein is useful for highlighting cell-cell contacts both in cultured cells and in tissue samples, outlining cell membranes and specific structures.
Where is ZO-1 expressed?
The protein is localized to the cytoplasmic membrane in most types of cells, particularly where a barrier function is essential. It is common in endothelial cells,4 which line the internal surface of blood and lymph vessels, and in epithelial cells,5 which form the outer barrier of organs.
ZO-1 is expressed in many tissues including the intestine, kidney, liver, and skeletal muscle cells.
What proteins does ZO-1 interact with?
The molecular weight of ZO-1 is 220kDa6 and it contains multiple distinct protein domains that allow bind to other junctional proteins at the cytoplasmic membrane. The N-terminal of ZO-1 can dimerize with other ZO proteins and bind directly to other TJ proteins including claudins, connexions, and JAMs,7-10 which allows it to assemble TJ complexes. The C-terminal can interact with actin and cortactin, anchoring the TJ complexes to the cytoskeleton.8,11 This suggests that ZO-1 forms a link between the outer cell-cell contacts and the inner actin.
