Disease relevance of ITGA3

 

High impact information on ITGA3

  • Anti-FRP-1 mAb immunoprecipitated gp80-85, gp120 and homodimers of these peptides, and anti-FRP-2 mAb reacted with gp135 identically to the alpha 3 subunit of integrin [4].
  • When activated by genotoxic stress or overexpressed ectopically in non-adherent cells, p51/p63 transduced a phenotype to attach to extracellular matrices, which was accompanied by expression of ITGA3 [5].
  • Additionally, the migratory CD4+ T cell population is largely CD58bright, CD31-, CD62L-, and is also enriched in cells that brightly express CD49c, CD49e, and CD49f [6].
  • IL-6 induced expression of CD49b (alpha-chain of VLA-2, 20% +/- 11 vs 2% +/- 1) and CD49c (alpha-chain of VLA-3, 43% +/- 17 vs 5% +/- 3), which are not expressed on resting NK cells [7].
  • CAP37 upregulated intercellular adhesion molecule (ICAM)-1, platelet endothelial cell adhesion molecule (PECAM)-1, and integrin molecules alpha3 (CD49c) and beta1 (CD29) [8].
 

Biological context of ITGA3

 

Anatomical context of ITGA3

 

Associations of ITGA3 with chemical compounds

  • CONCLUSIONS: In vivo selection and flow cytometric analysis revealed that Lea, sLea, CD49b, CD49c, and CD29 appear to be involved in the increase of metastatic activity [14].
  • Identification of human galactoprotein b3, an oncogenic transformation-induced membrane glycoprotein, as VLA-3 alpha subunit: the primary structure of human integrin alpha 3 [9].
  • Based on this sequence identity and the structural similarities (i.e. the positions of most cysteine residues, the presence of a transmembrane domain near the C-terminus and the presence of metal binding sequences) with other integrins so far cloned, we conclude that human galactoprotein b3 is an integrin alpha 3 subunit [9].
 

Other interactions of ITGA3

  • We investigated this by studying the expression of the beta1-integrin chains CD29 and CD49c, -d, -e, and -f, on in vitro HIV-infected primary T cells [15].
  • In pre-B ALL, expression of CD11a positively correlated with that of CD11b (P < .05) and CD54 (P < .01), and CD49c positively correlated with CD49f (P < .01) [16].
 

Analytical, diagnostic and therapeutic context of ITGA3

  • In the present study, we examined the change in the amounts of mRNA for the mouse and human counterparts in fibroblasts after oncogenic transformation by Northern blot analysis using hamster galactoprotein b3 cDNA as a probe [9].
  • Since VCA-2 is found predominantly on the basal membrane of adherent cells and its expression increases 12-fold when HUT-102 lymphoblastoid cells are grown as an adherent cell culture, we suggest that VCA-2 plays a role in cellular adherence [17].
