描述:
claudin 3 Plays a major role in tight junction-specific obliteration of the intercellular space, through calcium- independent cell-adhesion activity. Belongs to the claudin family. Can form homo- and heteropolymers with other CLDN. Homopolymers interact with CLDN1 and CLDN2 homopolymers. Directly interacts with TJP1/ZO-1, TJP2/ZO-2 and TJP3/ZO-3.

(I) IHC staining to identify EMT biomarkers and COMP-related proteins in the control, COMP knockdown, and COMP overexpression groups. COMP knockdown displayed strong E-cadherin staining and reduced Vimentin, Snail1, Twist1, and MMP-2 staining. The expression levels of other proteins were identical to those observed in WB experiments. (J) Staining indices of COMP, E-cadherin, Vimentin, Snail1, Twist1, and MMP2. The error bars in all graphs represented SD, and each experiment was repeated three times. * and ** stand for P<0.05 and P<0.01, respectively.
