Sensitivity of Protein Crystallization to Concentration Change

第五届中国结构生物学学术讨论会

作者： Da-Chuan Yin chen-Yan Zhang rui-qing chen chen Dong Qin-Qin Lu Hai Hou School of Life Sciences Northwestern Polytechnical University

Protein crystals are very useful in a number of fields like structural biology, pharmacy, protein purification, and materials sciences. In the field of structural biology, they are used for structural determination of protein molecules via X-ray, electron, or neutron diffraction. The first step to obtain protein crystals is to find out the crystallization agents that can help to crystalize the target proteins. This step is often challenging. Methods to tackle this challenge are therefore necessary. In this report, we will present a new crystallization plate design which can be used to expand the screening space for protein crystallization based on cross-diffusion microbatch（CDM） method[1]. The new plate consists of 96 units corresponding to the conditions of the commercial screening kits, and each unit contains four wells for holding the crystallization droplets. By dispensing crystallization droplets to the four wells at different volume ratios of protein to precipitant solutions, we can obtain four different initial concentrations for each unit, thus a wider concentration range can be screened. The comparison between the screening performance of the new plates and the traditional sitting-drop vapor diffusion plate showed that the new design of the plates exhibited significantly improved results in obtaining more crystallization conditions[2]. Similar concept can be utilized in expanding the p H screening space by adding extra buffer solutions to different wells, so as to realize screens with four different initial p H values simultaneously. The new crystallization plate can be made compatible with the SBS standard so that automation can be carried out easily. Apparently, the method is applicable in routine crystallization screening experiment, and hopefully it can be of use in the process of obtaining crystallization conditions.

Neural Regeneration Research 2025年第5期20卷 1258-1276页

The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u
