    text
  • concentrated in the junctional complex in various types of epithelial and endothelial cells
  • Furthermore, in the liver and kidney, also distributed along non-junctional actin filaments
  • is peripherally localized in isolated cells, requires the integrity of the microtubule cytoskeleton to be stably anchored to junctions
  • localized in the cytoplasmic region of epithelial tight and adherens junctions
  • CGN, CGNL1 and PLEKHA7 are proteins localized in the cytoplasmic region of the apical junctional complex of vertebrate epithelial cells
  • basic FUNCTION
  • involved in anchoring the apical junctional complex, especially tight junctions, to actin-based cytoskeletons
  • regulates the activity of RAC1 and RHOA GTPases by recruiting TIAM1 and ARHGEF2 to epithelial junctions
  • CGN and CGNL1 regulate Rho family GTPases by recruiting guanine nucleotide exchange factors to epithelial junctions
  • CGN1 and CGNL1 show a similar dynamic behaviour, but partially distinct localizations and functional interactions with the cytoskeleton, and are recruited independently to junctions
  • component of the macromolecular complex that links adherens junctions to microtubules, and PLEKHA7, and, to a lesser extent, TJP1, are required to recruit paracingulin to epithelial junctions efficiently
  • PLEKHA7, together with CNGL1, is part of a protein complex that links CDH1 to the microtubule cytoskeleton at AJs
  • functional relevance for CGNL1 as a defining factor in new vessel formation

    PATHWAY
    metabolism
    signaling
    a component
  • forms a complex with the tight junction protein TJP1, and the globular head domain of paracingulin interacts directly with TJP1 through an N-terminal region containing a conserved ZIM (ZO-1-Interaction-Motif) sequence
  • forms a complex with PLEKHA7 and its interacting partner CTNND1, and the globular head domain of paracingulin interacts directly with a central region of PLEKHA7
  • SH3BP1 formed a complex with CGNL1/paracingulin, a junctional adaptor, and CD2AP, a scaffolding protein, and both were required for normal CDC42 signaling and junction formation
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • regulator of the activity of two small GTPases, RAC1 and RHOA, through the functional interaction with their respective activators, TIAM1 and ARHGEF2
  • associates with E-cadherin, CDH1
  • TJP1 and the adherens junction protein PLEKHA7 as paracingulin-binding proteins
  • one function of CGN and CGNL1 is to regulate the activity of Rho family GTPases at junctions through their direct interaction with guanidine exchange factors of RHOA and RAC1
  • CGN and CGNL1 control RHOA activation in epithelial cells by interacting with RHOA guanidine exchange factors
  • regulates vascular growth by promoting CDH5 association with the actin cytoskeleton, thereby stabilizing adherens junctions
