FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for targeted null mutations were viable, fertile, showed no overt anatomical defects, and exhibited no bleeding anomalies. Platelet, primary fibroblast and keratinocytes from homozygous mutant mice show less efficient adhesion to collagens in vitro. [provided by MGI curators]
