BCL2L2（BCL2 like 2），癌症关联基因，基因ID：599，这个基因编码bcl-2蛋白家族的一个成员。这个家族的蛋白质形成异二聚体或同二聚体，并作为抗和促凋亡的调节因子。在细胞毒性条件下，该基因在细胞中的表达有助于减少细胞凋亡。对小鼠相关基因的研究表明，ngf和bdnf依赖神经元的存活与此有关。小鼠基因的突变和敲除研究表明在成年精子发生中起着重要作用。选择性剪接导致多个转录变体。该基因与邻近的下游pabpn1（poly（a）结合蛋白，nuclear 1）基因之间也存在读写转录。[由RefSeq提供，2010年12月]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。
