Definition / General
  • Pleckstrin-homology-domain-containing protein
  • PLEKHA7, cingulin and paracingulin are proteins localized in cytoplasmic region of apical junctional complex of vertebrate epithelial cells
  • PLEKHA7, together with paracingulin, is part of a protein complex that links E-cadherin to microtubule cytoskeleton adherens junctions
    • PLEKHA7 overexpression has inverse relation with E-cadherin expression
Clinical Features
Uses by Pathologists
  • PLEKHA7 overexpression may differentiate infiltrating lobular carcinoma from normal tissue / low grade infiltrating ductal carcinoma (PLEKHA7-, Hum Pathol 2012;43:1902)
