CD49a is a 200 kD type I transmembrane glycoprotein also known as α1 integrin, VLA-1 α chain, or Integrin α1. It associates with CD29 (β1 integrin) to form VLA-1 complex, a collagen IV and alminin-1 receptor. It is expressed on activated T cells, monocytes, NK cells, smooth muscle cells, neuronal cells, fibroblasts, and mesenchymal cells. CD49a is an adhesion molecule and is involved in the regulation of leukocyte migration, T cell proliferation, and cytokine production.
