    SUBCELLULAR LOCALIZATION     plasma membrane,junction,tight
    basic FUNCTION
  • major endothelial cell specific components of tight junction (TJ) strands regulating MMP14 during angiogenesis
  • tight junction specific obliteration of the intercelular space
  • creating charge specific channels in the paracellular space
  • classified as a tight-junctional protein capable of contributing to the "sealing" of the tight junction
  • increasing the airway tight junctional permeability (C
  • may participate in novel mechanisms in the pathway to end-stage heart failure
  • key determinant of trans-endothelial resistance at the blood-brain barrier
  • CDH5, NECTIN2, and CLDN5 are involved in the regulation of vascular permeability in a mutually interacting manner, which indicates their prominent role for the functionality of the human corpus luteum

    a component
  • major structural components of tight junction (TJ) strands
  • component of tight junctions in endothelial cell layers
    small molecule
  • promoting activation of promatrix metalloproteinase-2 mediated by membrane type matrix metalloproteinases
  • regulating MMP14 and promoting angiogenesis
  • interacting with SOX18 (SOX18 involved in the regulation of CLDN5 gene expression in an endothelial-specific and cell density-dependent manner, play a nonredundant role in the formation of the endothelial barrier)
  • CLDN5 is a downstream target of ERG in endothelial cells (EC)
  • GNAI2 interacts with CLDN5 and association is correlated with TJ (tight junctions) integrity in brain endothelial cell line
  • KLF4 regulates blood-tumor barrier permeability via TJP1, OCLN and CLDN5
  • cell & other
    activated by endothelial VE-cadherin (CDH5) at adherens junctions
    inhibited by VEGFA (that constitutes a significant mechanism in blood-brain barrier breakdown)
