present a 3D template-based metal site prediction (TEMSP ) to predict zinc binding sites and completed sensitivity of 0.86. combined two methods based on substructure and sequence (COACH ) to identify protein-ligand binding sites and achieved Matthews correlation coefficient (MCC) of 0.54. Over the last decade, computational methods have been made significant advances in identifying MIBs. These methods, computation-based, reduce the cost to discover the potential MIBs that also have near-accurate predictions. Previous extensive research on water-soluble proteins has provided ideas in computational methods for use as reference. With sequencing technology development, the time has come to study the work related to TMPs. However, these techniques had not achieved large-scale application compared to the water-soluble proteins since the TMPsвЂ™ folding, native structure, stability, and activity are reached only within the lipid bilayer. Exploring the TMPsвЂ™ metal ion binding site (MIBs) provides a practical means to explore the ion selectivity and crucial abilities and even further construct the ion transport mechanism.Д®xperimental techniques such as AFM, MS, IMAC, NMR, and X-ray crystallography are comprehensive to identify the crystal structures of protein and characterize the binding sites in proteins. However, knowledge about the transport mechanism of metal ions that bind to proteins across membranes is still insufficient and varies for different metals. TMPs, as the primary carrier of metal ions, participate in signal transduction, intracellular trafficking, and maintaining homeostasis.

These particular proteins cross through the biomembranes by their transmembrane domains and exist therein whole life, constitute 15-30% of the genome. According to the transport mode and spatial structure, the transporter protein can be roughly divided into channel and carrier proteins, all transmembrane proteins (TMPs).

Therefore, maintaining the correct levels of metal ions in the cytoplasm is essential for life and health.ДЄs we know, metal ions cannot directly penetrate the cell membrane unless the transporterвЂ™s assistance is on the cell membrane. Their homeostasis disorders involve neurodegenerative diseases, cardiovascular diseases, bone diseases, asthma, cancer, and diabetes. Also, other metal ions perform their respective biological functions. Zn 2+ is a multitasking tool necessary to stimulate various enzyme activities that lack and excess can cause central nervous system diseases. Mg 2+ regulates ion channelsвЂ™ activity in cardiac cells, affecting the myocardiumвЂ™s electrical properties. For example, Ca 2+ signaling is essential for T cell activation, autoantigen tolerance, differentiation, and development. They can enter cells to regulate the expression and activation of multiple biomolecules, participate in cell signal transduction, and complete various functions. Metal ions are vital to live organisms involving in various biological processes.

This paper explores the interaction mechanism between TMPs and metal ions, which is helpful to understand the structure and function of TMPs and is of great significance to further construct transport mechanisms and identify potential drug targets.

The results in the independent verification dataset show that TMP-MIBS has superior performance. Thereby, we compared our model with the published tools which do not distinguish TMPs from water-soluble proteins. At present, there is no specific research on the metal ion binding prediction of TMPs. To predict the metal ion binding sites for TMPs on a large scale, we present a simple and effective two-stage prediction method TMP-MIBS, to identify the corresponding binding residues using TMP sequences. The metal ion binding of transmembrane proteins (TMPs) plays a fundamental role in biological processes, pharmaceutics, and medicine, but it is hard to extract enough TMP structures in experimental techniques to discover their binding mechanism comprehensively.
