Product description |
CD49b, a member of the integrin family of extracellular matrix and cell adhesion molecules, is the integrin α2 chain. CD49b associates noncovalently with CD29, the integrin β1 subunit, to form the heterodimer integrin α2β1 that binds laminin and collagen. It is expressed on B and T lymphocytes, NK cells, monocytes, platelets, fibroblasts, and long-term cultured T cells. CD49b/CD29 mediates the Mg++-dependent adhesion of platelets to collagen. It may also be utilized by fibroblasts for the reorganization of the collagen matrix during wound healing. |
