    SUBCELLULAR LOCALIZATION
    text type I membrane protein
    basic FUNCTION
  • cell surface adhesion receptor mediating cell-adhesion to extra cellular matrix or to other cells, through hetero dimerization and connecting to the cytoskeleton and various signaling molecules within cells
  • allows retinal pigmented epithelial cells adhesion on Bruch's membrane in wet age-related macular degeneration (Afshari 2010)
  • can induce and localise to focal adhesions in a high activation state, whereas its intermediate activity state normally supports cell adhesion consistent with migration (Lydolph 2009)
  • contributing to adhesion and differentiation of hematopoietic stem and progenitor cells in the endosteal stem cell niche (Schreiber 2009)
  • critical intrinsic regulator that controls the development of autoimmune arthritis (Kanayama 2009)
  • involved in the attraction of neutrophils via its binding to osteopontin (Nishimichi 2009)
  • receptor for nerve growth factor, brain-derived neutrophic factor and NT3 (Staniszewska 2008)
