Entrez Gene Summary for TP53BP2 Gene

  • This gene encodes a member of the ASPP (apoptosis-stimulating protein of p53) family of p53 interacting proteins. The protein contains four ankyrin repeats and an SH3 domain involved in protein-protein interactions. It is localized to the perinuclear region of the cytoplasm, and regulates apoptosis and cell growth through interactions with other regulatory molecules including members of the p53 family. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for TP53BP2 Gene

TP53BP2 (Tumor Protein P53 Binding Protein 2) is a Protein Coding gene. Among its related pathways are ERK Signaling and GPCR Pathway. GO annotations related to this gene include identical protein binding and SH3/SH2 adaptor activity. An important paralog of this gene is PPP1R12C.

UniProtKB/Swiss-Prot for TP53BP2 Gene

  • Regulator that plays a central role in regulation of apoptosis and cell growth via its interactions. Regulates TP53 by enhancing the DNA binding and transactivation function of TP53 on the promoters of proapoptotic genes in vivo. Inhibits the ability of APPBP1 to conjugate NEDD8 to CUL1, and thereby decreases APPBP1 ability to induce apoptosis. Impedes cell cycle progression at G2/M. Its apoptosis-stimulating activity is inhibited by its interaction with DDX42.

    Molecular mass:
    125616 Da
    Quaternary structure:
    • Binds to the central domain of TP53 as well as to BCL2. Interacts with protein phosphatase 1. Interacts with RELA NF-kappa-B subunit. This interaction probably prevents the activation of apoptosis, possibly by preventing its interaction with TP53. Interacts with APC2 and APPBP1. Interacts with DDX42 (via the C-terminus); the interaction is not inhibited by TP53BP2 ubiquitination and is independent of p53/TP53.

Molecular function for TP53BP2 Gene

GENATLAS Biochemistry: TP53 binding protein 2,cytoplasmic not binding mutant TP53
UniProtKB/Swiss-Prot Function: Regulator that plays a central role in regulation of apoptosis and cell growth via its interactions. Regulates TP53 by enhancing the DNA binding and transactivation function of TP53 on the promoters of proapoptotic genes in vivo. Inhibits the ability of APPBP1 to conjugate NEDD8 to CUL1, and thereby decreases APPBP1 ability to induce apoptosis. Impedes cell cycle progression at G2/M. Its apoptosis-stimulating activity is inhibited by its interaction with DDX42.
UniProtKB/Swiss-Prot Induction: Following DNA damage induced by UV irradiation. Down-regulated by wild-type, but not mutant, p53/TP53.
