β-catenin

β-catenin is a protein that plays a key role in cell communication and regulation of gene activity. It is involved in the Wnt signaling pathway, which influences cell growth, development, and tissue maintenance. When Wnt signals are active, β-catenin accumulates in the cell’s nucleus, helping turn on genes necessary for cell proliferation and differentiation. Proper regulation of β-catenin is vital for normal development and tissue health. Abnormal levels or activity of β-catenin are linked to diseases like cancer, making it an important focus for medical research.
