      Background InformationIntegrins are a family of dimeric, transmembrane proteins that mediate cell-cell and extracellular matrix adhesion. Signals transduced by integrins play a role in many biological processes, including cell growth, differentiation, migration and apoptosis. The integrin family is composed of at least 19 alpha and 8 beta subunits that form over twenty different alpha-beta non-covalently bound dimeric combinations on the cell surface. Both of the subunits contribute to the binding of the ligand. The alpha-3 subunit (CD49c) is highly concentrated in epithelial cells where it strongly adheres to Laminin-5 and Laminin-5 induced rapid adhesion can be blocked by antibodies against the alpha-3 integrin subunit. The alpha-3 subunit exists in two different splice variants, denoted as "A" and "B". The only difference that results from this differential splicing is a total change in the cytoplasmic domain, while the extracellular domain stays the same. Knock-out mice lacking this subunit show prenatal lethality and abnormalities in the kidneys.

      Key Applications
      • ELISA
      • Immunofluorescence
      • Immunohistochemistry
      • Immunoprecipitation
      • Radioimmunoassay
      • Western Blotting
      Application NotesELISA/RIA:
      A 1:1,000 dilution of a previous lot was used in Enzyme-linked Immunosorbent Assay/Radioimmunoassay.

      5 µL of a previous lot precipitated alpha3/beta1 from 5 x 106 cells (Sherry, D.M., 2001).

      1:500 dilution of a previous lot was used, suggest use on acetone-fixed tissue.

      Western Blot Analysis:
      1:500 dilution of a previous lot was used.

      Optimal working dilutions must be determined by end user.
      Biological Information
      ImmunogenA synthetic peptide (CRIQPSETERLTDDY) derived from the COOH terminal sequence located in the cytoplasmic domain of the human alpha3 integrin subunit.
      EpitopeCytoplasmic domain
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityIntegrin alpha3. Specificity determined by immunoprecipitation from a detergent extract of 35S-methionine labeled neuroblastoma cells. No cross-reactivity to alpha1, alpha2, alpha4, alpha5, alpha6, or alphaV integrins.

      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.
