| 释义 | ITGA2ITGA2A gene on chromosome 5q11.2 that encodes an integrin alpha chain protein which, like all integrins, forms a heterodimer with a beta chain, thereby participating in an array of cell-cell and cell-matrix interactions, playing a major role in cell migration, organ and tissue development and differentiation. Alpha-2 beta-1 heterodimers serve as receptors for laminin, collagen, collagen C-propeptides, fibronectin and E-cadherin, and is responsible for adhesion of platelets and other cells to the extracellular matrix, modulation of collagen and collagenase gene expression and organisation of newly synthesised extracellular matrix. |
