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]
Forensic Context
A study in human cadavers demonstrated that the TP53BP2 was highly expressed at later postmortem intervals (96 h and 120 h) in prostate tissues, showing significant upregulation in Groups 3 and 4 compared to a 24-hour control, as validated by PCR Array analysis [Tolbert et al. DOI:10.1016/j.gene.2018.06.090].
