Entrez Gene Summary for ITGA5 Gene

  • The product of this gene belongs to the integrin alpha chain family. Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain. This gene encodes the integrin alpha 5 chain. Alpha chain 5 undergoes post-translational cleavage in the extracellular domain to yield disulfide-linked light and heavy chains that join with beta 1 to form a fibronectin receptor. In addition to adhesion, integrins are known to participate in cell-surface mediated signalling. Integrin alpha 5 and integrin alpha V chains are produced by distinct genes.

GeneCards Summary for ITGA5 Gene

ITGA5 (Integrin, Alpha 5 (Fibronectin Receptor, Alpha Polypeptide)) is a Protein Coding gene. Diseases associated with ITGA5 include gastric cardia adenocarcinoma. Among its related pathways are PI3K-Akt signaling pathway and Proteoglycans in cancer. GO annotations related to this gene include integrin binding and vascular endothelial growth factor receptor 2 binding. An important paralog of this gene is ITGA8.

UniProtKB/Swiss-Prot for ITGA5 Gene

  • Integrin alpha-5/beta-1 is a receptor for fibronectin and fibrinogen. It recognizes the sequence R-G-D in its ligands. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposis sarcoma lesions

Tocris Summary for ITGA5 Gene

  • Integrins are ubiquitously expressed adhesion molecules. They are cell-surface receptors that exist as heterodimers of alpha and beta subunits. At physiological conditions, integrins are highly glycosylated and contain a Ca2+ or Mg2+ ion, which is essential for ligand binding. Integrin receptors are critical for cell attachment to the extracellular matrix (ECM) and this is mediated through integrin-fibronectin, -vitronectin, -collagen and -laminin interactions. Intracellularly, integrins form adhesion complexes with proteins including talin, vinculin, paxillin and alpha-actinin. They also regulate kinases, such as focal adhesion kinase and Src family kinases, to mediate attachment to the actin cytoskeleton. Integrins also have a significant role in cell signaling and can activate protein kinases involved in the regulation of cell growth, division, survival, differentiation, migration and apoptosis. Glycoprotein II/IIIb (alphaIIbeta3) is an integrin receptor found on the surface of platelets. It is involved in the cross-linking of platelets with fibrin, and so has a vital role in blood clot formation.
