      Background InformationIntegrins are a family of dimeric proteins that mediate cell-cell and extracellular matrix adhesion. Each VLA subtype (VLA-1, VLA-2, VL-3, VLA-4, VLA-5) is composed of a distinct alpha subunit noncovalently associated with a common beta subunit, as an alpha-beta dimer. Integrin VLA-3 (very late antigen, alpha-3/beta-1) is a cell surface receptor that binds to fibronectin, laminin, collagen type I and VI. VLA-3 is typically restricted in normal tissue but is widely expressed in many cultured tumor cells and correlates with the degree of invasiveness of malignant melanoma cells.

      Key Applications
      • ELISA
      • Immunoprecipitation
      • Radioimmunoassay
      • Immunocytochemistry
      • Immunohistochemistry (Paraffin)
      Application Notes

      Immunohistochemistry (works on Acetone-fixed paraffin-embedded tissues)

      ELISA/RIA

      Immunoprecipitation. When immunoprecipitated samples are run on SDS-PAGE under a) non-reducing conditions, two bands will be detected with an apparent molecular weight of 110 and 150kDa; and b) reducing (2% B-ME) conditions, a single molecular species of 130kDa is detected. Under reducing conditions both alpha3 and beta1 subunits run with the same apparent molecular weight.

      Optimal working dilutions must be determined by end user.

      Entrez Gene Number
      Entrez Gene SummaryITGA3 encodes the integrin alpha 3 chain. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. Alpha chain 3 undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light and heavy chains that join with beta 1 to form an integrin that interacts with many extracellular-matrix proteins. The alpha 3 beta 1 integrin is known variously as: very late (activation) antigen 3 ('VLA-3'), very common antigen 2 ('VCA-2'), extracellular matrix receptor 1 ('ECMR1'), and galactoprotein b3 ('GAPB3').

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P26006 # Integrin alpha-3/beta-1 is a receptor for fibronectin, laminin, collagen, epiligrin, thrombospondin and CSPG4. Alpha- 3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration.
      SIZE: 1066 amino acids; 118698 Da
      SUBUNIT: Heterodimer of an alpha and a beta subunit. The alpha subunit is composed of an heavy and a light chain linked by a disulfide bond. Alpha-3 associates with beta-1. Interacts with HPS5.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      TISSUE SPECIFICITY: Isoform alpha-3A is widely expressed. Isoform alpha-3B is expressed in brain and heart. In brain, both isoforms are exclusively expressed on vascular smooth muscle cells, whereas in heart isoform alpha-3A is strongly expressed on vascular smooth muscle cells, isoform alpha-3B is detected only on endothelial vein cells.
      PTM: Isoform alpha-3A, but not isoform alpha-3B, is phosphorylated on serine residues. Phosphorylation increases after phorbol 12- myristate 13-acetate stimulation.
      SIMILARITY: SwissProt: P26006 ## Belongs to the integrin alpha chain family. & Contains 7 FG-GAP repeats.
