CD49b, also known as integrin alpha-2, is a protein encoded by the CD49b gene in humans. It is a subunit of the integrin receptor family, specifically forming the VLA-2 receptor when paired with the beta-1 subunit. This receptor is primarily involved in mediating cell adhesion to collagen and laminin, playing a crucial role in various biological processes such as platelet aggregation, cell migration, and tissue repair. CD49b is expressed on various cell types, including natural killer cells and a subset of T cells, and has been implicated in immune responses and cancer progression. In cancer research, CD49b has been identified as a potential therapeutic target due to its role in promoting cell proliferation and invasion in certain malignancies.
