    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
  • mediating cell-extracellular matrix interactions also involved in the fertilization and embryonic development
  • distinct roles of ITGA6 and ITGA4 in homing of fetal liver hematopoietic stem and progenitor cells
  • major role in the proangiogenic properties of endothelial colony-forming cells (ECFCs)
  • regulates signaling pathways in a variety of cellular activities
  • cell-surface protein, having novel and dynamic roles in regulating the differentiation potential of mesenchymal stem cells and maintaining pluripotency
  • CELLULAR PROCESS cell communication
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • constituent of VLA-6 receptor
  • dimerizing with ITGB1 (laminin receptor) or ITGB4 (constituent of hemidesmosome)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • synergistic role for TAF4B and JUN and other AP1 family members on the promoter of ITGA6, underlining the existence of a specific mechanism related to gene expression control
