ITGA2 - integrin subunit alpha 2 Gene
Also Known as BR; GPIa; CD49B; HPA-5; VLA-2; VLAA2
Species: Homo sapiens
About ITGA2
This gene has 6 transcripts (splice variants), 240 orthologues, 17 paralogues and is associated with 1 phenotype. Broad expression in skin (RPKM 8.4), adrenal (RPKM 7.9) and 21 other tissues.
Summary
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]
