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]
TP53BP2 (Tumor Protein P53 Binding Protein 2) is a Protein Coding gene. Diseases associated with TP53BP2 include Chromosome 1Q41-Q42 Deletion Syndrome and Lung Cancer. Among its related pathways are Beta-Adrenergic Signaling and ERK Signaling. Gene Ontology (GO) annotations related to this gene include identical protein binding and p53 binding. An important paralog of this gene is PPP1R13B.
