This gene encodes a member of the BCL-2 protein family. The proteins of this family form hetero- or homodimers and act as anti- and pro-apoptotic regulators. Expression of this gene in cells has been shown to contribute to reduced cell apoptosis under cytotoxic conditions. Studies of the related gene in mice indicated a role in the survival of NGF- and BDNF-dependent neurons. Mutation and knockout studies of the mouse gene demonstrated an essential role in adult spermatogenesis. Alternative splicing results in multiple transcript variants. Read-through transcription also exists between this gene and the neighboring downstream PABPN1 (poly(A) binding protein, nuclear 1) gene. [provided by RefSeq, Dec 2010]
Forensic Context
A study in human cadavers demonstrated that the BCL2L2 was down-regulated (-102.6198 fold) in decaying liver tissues compared to a control [Javan et al. DOI:10.1007/S12024-015-9704-6]. In a separate investigation of human prostate tissues, the BCL2L2 was significantly upregulated at longer postmortem intervals (96 and 120 hours) compared to a 24-hour control [Tolbert et al. DOI:10.1016/j.gene.2018.06.090].
