| 3 | Functional divergence of oligoadenylate synthetase 1(OAS1)proteins in Tetrapods显示文摘OASs play critical roles in immune response against virus infection by polymerizing ATP into 2-5 As,which initiate the classical OAS/RNase L pathway and induce degradation of viral RNA.OAS members are functionally diverged in four known innate immune pathways(OAS/RNase L,OASL/IRF7,OASL/RIG-I,and OASL/cGAS),but how they functionally diverged is unclear.Here,we focus on evolutionary patterns and explore the link between evolutionary processes and functional divergence of Tetrapod OAS1.We show that Palaeognathae and Primate OAS1 genes are conserved in genomic and protein structures but differ in function.The former(i.e.,ostrich)efficiently synthesized long 2-5 A and activated RNase L,while the latter(i.e.,human)synthesized short 2-5 A and did not activate RNase L.We predicted and verified that two in-frame indels and one positively selected site in the active site pocket contributed to the functional divergence of Palaeognathae and Primate OAS1.Moreover,we discovered and validated that an in-frame indel in the C-terminus of Palaeognathae OAS1 affected the binding affinity of ds RNA and enzymatic activity,and contributed to the functional divergence of Palaeognathae OAS1 proteins.Our findings unravel the molecular mechanism for functional divergence and give insights into the emergence of novel functions in Tetrapod OAS1. | Xiaoxue Wang Jiaxiang Hu Linfei Song Enguang Rong Chenghuai Yang Xiaoyun Chen Juan Pu Honglei Sun Chuze Gao David WBurt Jinhua Liu Ning Li Yinhua Huang | 2022 | Science China(Life Sciences)2022，65，7： | 1 |
| 4 | Shallowing interfacial carrier trap in transition metal dichalcogenide heterostructures with interlayer hybridization显示文摘With the unique properties,layered transition metal dichalcogenide(TMD)and its heterostructures exhibit great potential for applications in electronics.The electrical performance,e.g.,contact barrier and resistance to electrodes,of TMD heterostructure devices can be significantly tailored by employing the functional layers,called interlayer engineering.At the interface between different TMD layers,the dangling-bond states normally exist and act as traps against charge carrier flow.In this study,we propose a technique to suppress such carrier trap that uses enhanced interlayer hybridization to saturate dangling-bond states,as demonstrated in a strongly interlayer-coupled monolayer-bilayer PtSe2 heterostructure.The hybridization between the unsaturated states and the interlayer electronic states of PtSe2 significantly reduces the depth of carrier traps at the interface,as corroborated by our scanning tunnelling spectroscopic measurements and density functional theory calculations.The suppressed interfacial trap demonstrates that interlayer saturation may offer an efficient way to relay the charge flow at the interface of TMD heterostructures.Thus,this technique provides an effective way for optimizing the interface contact,the crucial issue exists in two-dimensional electronic community. | Xu Wu Jingsi Qiao Liwei Liu Yan Shao Zhongliu Liu Linfei Li Zhili Zhu Cong Wang Zhixin Hu Wei Ji Yeliang Wang Hongjun Gao | 2021 | Nano Research2021，14，5： | 0 |
