Summaries for ITGA2 Gene

Entrez Gene Summary for ITGA2 Gene

  • This gene encodes the alpha subunit of a transmembrane receptor for collagens and related proteins. The encoded protein forms a heterodimer with a beta subunit and mediates the adhesion of platelets and other cell types to the extracellular matrix. Loss of the encoded protein is associated with bleeding disorder platelet-type 9. Antibodies against this protein are found in several immune disorders, including neonatal alloimmune thrombocytopenia. This gene is located adjacent to a related alpha subunit gene. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

GeneCards Summary for ITGA2 Gene

ITGA2 (Integrin Subunit Alpha 2) is a Protein Coding gene. Diseases associated with ITGA2 include glycoprotein ia deficiency and thrombocytopenia. Among its related pathways are Platelet activation, signaling and aggregation and Sertoli-Sertoli Cell Junction Dynamics. GO annotations related to this gene include protein heterodimerization activity and integrin binding. An important paralog of this gene is ITGA8.

UniProtKB/Swiss-Prot for ITGA2 Gene

  • Integrin alpha-2/beta-1 is a receptor for laminin, collagen, collagen C-propeptides, fibronectin and E-cadherin. It recognizes the proline-hydroxylated sequence G-F-P-G-E-R in collagen. It is responsible for adhesion of platelets and other cells to collagens, modulation of collagen and collagenase gene expression, force generation and organization of newly synthesized extracellular matrix.

  • (Microbial infection) Integrin ITGA2:ITGB1 acts as a receptor for human rotavirus A (PubMed:12941907). Integrin ITGA2:ITGB1 acts as a receptor for human echoviruses 1 and 8 (PubMed:8411387).
