Integrin beta 6 is a subunit of integrins, which are heterodimeric cell surface receptors composed of an alpha and a beta subunit. Integrin beta 6 specifically pairs with integrin alpha M （also known as CD11b） to form the integrin αMβ6 complex. This complex is known for its role in cell adhesion, migration, and signaling processes, particularly in the context of immune responses and tissue repair. Research has implicated integrin β6 in the regulation of inflammation and immune cell function. It is involved in the activation and recruitment of immune cells to sites of injury or infection. Moreover, integrin β6 has been linked to the pathogenesis of several diseases, including cancer, where it may contribute to tumor progression and metastasis by modulating epithelial-mesenchymal transition （EMT） and promoting cancer stem cell properties.
