Background Information
TP53BP2 is also named as ASPP2, BBP and 53BP2. TP53BP2 is a regulator that plays a central role in regulation of apoptosis and cell growth via its interactions with proteins such as TP53 (PMID: 12524540). Numerous in vitro and animal experiments have shown that reduced TP53BP2 expression can inhibit apoptosis of tumor cells, cause malignant proliferation, disrupt cell polarity, promote cell migration, and enhance autophagy and drug resistance to chemotherapy (PMID: 37492707). In terms of autophagy, the decrease of TP53BP2 expression enhances autophagy in hepatocellular carcinoma (HCC) cells, promoting the survival and drug resistance of HCC cells. TP53BP2 can interact with p53, NF-κB p65, Bcl-2, HCV core protein, PP1, YAP, CagA, RAS, PAR3, and other proteins to regulate cell function. TP53BP2 can also regulate the proliferation, apoptosis, autophagy, migration, EMT and drug resistance of tumor cells through downstream signaling pathways, such as NF-κB, RAS/MAPK, mevalonate, TGF-β1, PI3K/AKT, aPKC-ι/GLI1 and autophagy pathways (PMID: 37492707).
