BH3-only proteins are key regulators of Bcl-2 family members to activate apoptosis. The absence of a BH3-only protein in Drosophila has complicated the understanding of how Bcl-2 family members contribute to cell death in this model organism. Recent work published in The EMBO Journal reports on the identification of a BH3-only protein in flies. The reported findings may help to clarify the functional role and molecular mechanisms of the highly conserved Bcl-2 pathway in divergent organisms.
BH3 仅蛋白是激活细胞凋亡的 Bcl-2 家族成员的关键调节剂。在果蝇中缺乏 BH3 仅蛋白,这使得理解 Bcl-2 家族成员如何促进该模型生物中的细胞死亡变得复杂。最近发表在《The EMBO Journal》上的一项研究报告了果蝇中 BH3 仅蛋白的鉴定。这些研究结果可能有助于阐明高度保守的 Bcl-2 途径在不同生物中的功能作用和分子机制。
