      • VLA-4
      Background InformationVirtually all lymphoid and myeloid cells in bone marrow are reactive with the anti-VLA-4 antibody. VLA-4 is absent or minimally detectable on stromal cells. Myeloid cells maintained in Dexter-type long-term cultures of murine bone marrow are positive, as are lymphoid cells from Whitlock-White cultures.

      Entrez Gene Number
      Entrez Gene SummaryThe product of this gene belongs to the integrin alpha chain family of proteins. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes an alpha 4 chain. Unlike other integrin alpha chains, alpha 4 neither contains an I-domain, nor undergoes disulfide-linked cleavage. Alpha 4 chain associates with either beta 1 chain or beta 7 chain.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P13612 # Integrins alpha-4/beta-1 (VLA-4) and alpha-4/beta-7 are receptors for fibronectin. They recognize one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. They are also receptors for VCAM1. Integrin alpha- 4/beta-1 recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha- 4/beta-7 is also a receptor for MADCAM1. It recognizes the sequence L-D-T in MADCAM1. On activated endothelial cells integrin VLA-4 triggers homotypic aggregation for most VLA-4-positive leukocyte cell lines. It may also participate in cytolytic T-cell interactions with target cells.
      SIZE: 1038 amino acids; 115333 Da
      SUBUNIT: Heterodimer of an alpha and a beta subunit. The alpha subunit can sometimes be cleaved into two non-covalently associated fragments. Alpha-4 associates with either beta-1 or beta-7. Alpha-4 interacts with PXN, LPXN, and TGFB1I1/HIC5. Interacts with CSPG4 through CSPG4 chondroitin sulfate glycosaminoglycan.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      DOMAIN: SwissProt: P13612 The SG1 motif is involved in binding to chondroitin sulfate glycosaminoglycan and cell adhesion.
      PTM: Phosphorylation on Ser-1027 inhibits PXN binding.
      SIMILARITY: Belongs to the integrin alpha chain family. & Contains 7 FG-GAP repeats.
