Target Data

Function Integrin ITGAL/ITGB2 is a receptor for ICAM1, ICAM2, ICAM3 and ICAM4. Integrins ITGAM/ITGB2 and ITGAX/ITGB2 are receptors for the iC3b fragment of the third complement component and for fibrinogen. Integrin ITGAX/ITGB2 recognizes the sequence G-P-R in fibrinogen alpha-chain. Integrin ITGAM/ITGB2 recognizes P1 and P2 peptides of fibrinogen gamma chain. Integrin ITGAM/ITGB2 is also a receptor for factor X. Integrin ITGAD/ITGB2 is a receptor for ICAM3 and VCAM1. Contributes to natural killer cell cytotoxicity

  1. The LFA-1-ICAM-1 orientation described here with ICAM-1 pointing anti-parallel to the LFA-1 beta-subunit leg is the same orientation that would be stabilized by tensile force transmitted between the ligand and the actin cytoskeleton and is consistent with the cytoskeletal force model of integrin activation. PMID: 29507098
  2. LncRNA ITGB2-AS1 could promote the migration and invasion of breast cancer cells by up-regulating ITGB2. PMID: 29941860
  3. Overexpression of ITGB2 was not correlated with ITGB2 promoter hypomethylation in systemic sclerosis. PMID: 29356883
  4. actin engagement produces tension within the beta2 subunit to induce and stabilize an active integrin conformational state and that this requires intact talin and kindlin motifs. PMID: 27721490
  5. on tumour-infiltrating T-lymphocytes, galectin prevents the formation of a functional secretory synapse by preventing optimal LFA-1 triggering PMID: 27447355
  6. exploration of the underlying mechanism demonstrated that ICAM3 not only binds to LFA-1 with its extracellular domain and structure protein ERM but also to lamellipodia with its intracellular domain which causes a tension that pulls cells apart (metastasis). PMID: 29729315
  7. vesicle-associated RhoB is a regulator of the Rab11-mediated recycling of LFA-1 to the cell surface, an event that is necessary for T lymphocyte motility. PMID: 29233918
  8. The ITGB2 variant rs2230531 was examined in an independent cohort of Tasmanian patients with hematologic malignancies (HM) to see if its presence correlated with chronic lymphocytic leukemia. The variant was found in several lymphoid and myeloid HMs, so if contributes to the risk of HM, it does so broadly across HM subtypes in this population. PMID: 28490571
  9. an integrated strategy of whole genome and transcriptome analysis enabled identification of LB-ITGB2-1 as HLA-B*15:01-restricted MiHAs encoded by an alternative transcript. The alternative ITGB2 transcript was shown to be expressed in leukemic cells of different origins. PMID: 26964570
  10. Neutrophil rolling over E-selectin at precise shear stress transmits tension and catch-bond formation with L-selectin via sLe(x), resulting in focal clusters that deliver a distinct signal to upshift beta2-integrins to a high-affinity state.

  18. K152 and D120 within the PH domain of SKAP55 regulate plasma membrane targeting and T cell receptor-mediated activation of LFA-1. PMID: 28052935
  19. Genetic inactivation and blockade studies revealed that homophilic interactions between intercellular adhesion molecule 1 (ICAM-1) expressed on tumor cells and MSCs, respectively, regulate the competition between tumor cells and HSPCs for binding to MSCs. Moreover, tumor cell-secreted soluble ICAM-1(sICAM-1) also impaired HSPC adhesion via blocking CD18-ICAM-1 binding between HSPCs and MSCs PMID: 27207667
  20. The ability of simvastatin to target CR3 in its ligand binding-activated conformation is a novel mechanism to explain the known anti-inflammatory effects of this compound, in particular because this CR3 conformation is found in pro-inflammatory environments. PMID: 27339893
