ITGB8 (Integrin Subunit Beta 8): ITGB8 is a protein involved in cell adhesion and signal transduction, mediating interactions between cells and the extracellular matrix. It plays a key role in tissue remodeling, angiogenesis, and brain development by facilitating the activation of transforming growth factor-beta (TGF-beta), a cytokine that regulates cell proliferation, differentiation, and other critical functions. Dysregulation of ITGB8 has been linked to cancer progression, as well as various vascular and neurological disorders, highlighting its essential role in cellular communication and disease.
