Diagram shows that UHRF1 is a junction protein involved in signal transduction. UHRF1 participates in signal transduction by interacting with different proteins. A: The UHFR1-BRCA1 interaction regulates DNA damage response; B: The N-terminal binding of YAP1 and UHRF1 promotes cell proliferation; C: The PARP1 and UHRF1 SRA domain binding complex inhibits gene transcription activity; D: The interaction between PP2A and UHRF1 SRA domain affects the activity of AMPK. YAP1: Yes-associated protein 1; DNMT1: DNA (cytosine-5)-methyltransferase 1; PARP1: Poly (ADP-ribose) Polymerase 1; PP2A: Protein Phosphatase 2A; AMPK: AMP-activated protein kinase; BRCA1: Breast Cancer susceptibility gene 1
