這個基因編碼bcl-2蛋白家族的一個成員。這個家族的蛋白質形成異二聚體或同二聚體，并作為抗和促凋亡的調節因子。在細胞毒性條件下，該基因在細胞中的表達有助于減少細胞凋亡。對小鼠相關基因的研究表明，ngf和bdnf依賴神經元的存活與此有關。小鼠基因的突變和敲除研究表明在成年精子發生中起著重要作用。選擇性剪接導致多個轉錄變體。該基因與鄰近的下游pabpn1（poly（a）結合蛋白，nuclear 1）基因之間也存在讀寫轉錄。[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. [provided by RefSeq, Dec 2010]
