Tumor suppressor p53-binding protein 1 also known as p53-binding protein 1 or 53BP1 is a protein that in humans is encoded by the TP53BP1 gene.[1][2][3]

Clinical significance[edit]

53BP1 is underexpressed in most cases of triple-negative breast cancer.[4]

Interactions[edit]

53BP1 has been shown to interact with:
