Integrin alpha 2 also known as CD49b ITGA2 and A2 is a protein that functions as part of the integrin family. Integrins are transmembrane receptors that facilitate cell-extracellular matrix adhesion. Integrin alpha 2 has a molecular mass of approximately 130 kDa and is widely expressed in epithelial cells fibroblasts and platelets. This protein is important for mediating adhesion between cells and the extracellular matrix affecting cell signaling and behavior. Through this adhesion cells can communicate with their environment adjusting their functions accordingly.
Integrin alpha 2 plays a significant role in cellular processes like migration and proliferation. It forms a heterodimer complex by pairing with the beta 1-integrin subunit contributing to its adhesive and signaling functions. This association enables the integrin alpha 2 complex to bind specific extracellular matrix components such as collagen and laminin. Through these interactions it regulates processes like wound healing and tissue remodeling and affects how cells respond to mechanical stress.
Integrin alpha 2 is involved in major signaling routes that influence cell fate and movement. Notably it participates in the PI3K/AKT and MAPK pathways which are important for regulating cell growth and survival. It interacts with signaling proteins like focal adhesion kinase (FAK) and Src family kinases linking extracellular matrix changes to intracellular responses. These pathways help in transmitting signals that coordinate the cell's structural and functional adjustments in response to its surroundings.
Integrin alpha 2 has connections to cancer and fibrosis. In cancers its altered expression may contribute to tumor progression and metastasis often involving interactions with other integrins and matrix metalloproteinases that degrade extracellular components. In fibrosis excessive integrin alpha 2 activity can lead to abnormal tissue remodeling and scarring implicating its role alongside collagen-producing cells. Understanding these connections is vital for developing therapies targeting integrin-mediated pathways in these diseases.
