Nature Biotechnology:AI 不仅开始设计蛋白质,还开始设计蛋白质在细胞内的去向。
DeepSCan 学习细胞表面展示的规则,并生成新的膜展示模块,其中多个模块的性能优于天然强序列。
这是迈向可编程细胞工程的一步。

数据可用性
本研究所有支持研究结果的主要数据均可在文章内以及通过 Zenodo(https://doi.org/10.5281/zenodo.19179097(ref.62 (https://www.nature.com/articles/s41587-026-03144-x#ref-CR62)))获取。源数据 (https://www.nature.com/articles/s41587-026-03144-x#Sec31)随本文一并提供。
代码可用性
蛋白质语言模型使用其官方 GitHub 代码库中提供的代码和预训练参数实现,并遵循相应说明。ESM2 代码和模型可通过 GitHub(https://github.com/facebookresearch/esm)获取。我们使用 RAPIDS cuML 库中的 XGBoost 和其他经典机器学习模型(如逻辑回归、随机森林),以利用图形处理器(GPU)加速训练。微调后的深度学习模型检查点及源代码将公开发布在 Hugging Face、Docker 和 Github(https://github.com/fangzhe3/DeepSCan)57 上 (https://www.nature.com/articles/s41587-026-03144-x#ref-CR57)。该 GitHub 代码库还介绍了使用 DeepSCan 网络服务器或 Docker 镜像的三个演示场景。Genesis Quant 8,000 模型的 Docker 镜像使用户能够利用 GPU 处理大规模序列分析。补充软件包含 DeepSCan 网络服务器应用程序(版本:app_v7.0_deployed_on_AWS)、Genesis 模型训练代码(版本:Genesis_Quant_8k_attention_pooling2_LLRD_v2)、Genesis 和 Omni 模型推理代码以及其他计算分析代码。DeepSCan 模型基于 Python(v.3.11.5)+ PyTorch(v.2.5.1,CUDA v.12.4)工作流。
