Publication number: 20240108743Abstract: A linker peptide for constructing a fusion protein. The linker peptide comprises a flexible peptide and a rigid peptide. The flexible peptide consists of one or more flexible units. The rigid peptide consists of one or more rigid units. The flexible unit comprises two or more amino acid residues selected from Gly, Ser, Ala, and Thr. The rigid unit comprises a human chorionic gonadotropin ?-subunit carboxy-terminal peptide (CTP) bearing a plurality of glycosylation sites. The linker peptide can more effectively eliminate mutual steric hindrance of two fusion molecules, decreasing a reduction/loss of polymerization or activity resulting from improper folding of an active protein or a conformational change. On the other hand, the negatively charged, highly sialylated CTP can resist renal clearance, further prolonging a half-life of a fused molecule and enhancing bioavailability of a fused protein.Type: ApplicationFiled: October 24, 2023Publication date: April 4, 2024Inventors: Qiang LI, Yuanli LI, Si CHEN, Zhu WANG, Zhao DONG, Zirui LI, Xinlu MA, Lu YANG, Yongjuan GAO, Yuncheng ZHENG, Naichao SUN

Publication number: 20230342663Abstract: A machine learning application method, a device, an electronic apparatus, and a storage medium, used to directly link service scenarios, aggregate data related to the service scenarios, accordingly explore modeling schemes, and ensure that data used in offline modeling scheme exploration and data used in an online model prediction service have the same source, thereby realizing consistency of source of offline and online data. Directly deploying an offline model to an online environment results in data inconsistency between online feature computation and offline feature computation, which in turn causes poor prediction performance; therefore, only a modeling scheme is deployed online, and the offline model is not deployed. After a modeling scheme is deployed online, sample data having a feature and feedback can be obtained by receiving a prediction request, thereby enabling model self-learning by means of the sample data.Type: ApplicationFiled: May 17, 2021Publication date: October 26, 2023Inventors: Qing ZHANG, Zhenhua ZHOU, Shijian ZHANG, Guangchuan SHI, Rong FANG, Yuqiang CHEN, Wenyuan DAI, Zhao ZHENG, Yingning HUANG
