Description

Application of HrpNECh protein in pharmacy for recognizing and activating multiple types of receptors and/or membrane proteins and signal pathways thereof
Technical Field
The invention relates to the field of biomedicine, in particular to application of an HrpNECh protein in pharmacy for recognizing and activating multiple receptors and/or membrane proteins and signal paths thereof and causing cascade biological effects.
Background
Molecular biology is the science of studying life phenomena at the molecular level, elucidating the nature of various life phenomena by studying the structure, function and metabolism of biological macromolecules, and its content covers the entire course of life. DNA, RNA and proteins are three important biological macromolecules and are the molecular basis for life phenomena. The genome determines what life is, the proteome determines what life can do, and the metabolome determines what life actually happens. Modern life science, biotechnology and medical biotechnology, especially proteomics and metabonomics, have been developed rapidly, the ideas of understanding, diagnosing, preventing and controlling, treating and recovering diseases are updated, new understanding and new ways of novel efficient and safe medicines are created, the development of modern medicine enters a brand-new stage, and a wide application prospect is opened up.
The receptor theory of modern life science is one of the basic theories of pharmacodynamics, and is an important basis for explaining the controllable physiological process and pathological process of life, the pharmacological action mechanism of drugs and the structural effect relationship of drug molecules from the molecular level. The ligand is a signal substance which has no other direct functions except for recognizing, binding and activating the receptor, cannot participate in metabolism to produce useful products, does not directly induce any cellular activity, and has no characteristics of enzyme.
The signal path (cell communication) is a communication mechanism for transmitting and receiving information in cells or cells of a multicellular organism with high accuracy and high efficiency, and a rapid cell physiological and biochemical reaction is caused by amplification or gene activity is started, and then a series of cell physiological and biochemical activities are generated to coordinate the activities of various tissues, so that the unified whole life can comprehensively react to changeable internal and external environments, and the coordinated joint mechanism for growth, development, defense and metabolism is built by systems, tissues, organs, cells, subcells, molecules and sub-molecules of a living organism.
The receptor is a functional protein for mediating cell signal transduction, can recognize certain trace substances in the surrounding environment (intracellular and extracellular environments), is recognized and combined with the trace substances, is activated, and triggers subsequent physiological and biochemical reactions through a signal amplification system. Receptors are biological macromolecules composed of cell membranes and intracellular proteins, nucleic acids, lipids, polysaccharides, and the like. Receptors are a broad concept in cell biology, meaning any biological macromolecule capable of binding to hormones, neurotransmitters, drugs or signaling molecules both inside and outside the cell and causing a change in cell function, in which case the signaling molecule is called a ligand. There are hundreds of different signaling molecules in multicellular organisms that transmit information between and within cells, including proteins, amino acid derivatives, nucleotides, cholesterol, fatty acid derivatives, and soluble gas molecules. Receptors present on the plasma membrane of cells are called membrane receptors, the chemical nature of which is for the most part sugar mosaics; receptors located in the cytosol and nucleus, called intracellular receptors, are all DNA binding proteins.
The ligand is a signal substance which has no other direct functions except for recognizing, binding and activating the receptor, cannot participate in metabolism to produce useful products, does not directly induce any cellular activity, and has no characteristics of enzyme.
The combination of ligand and receptor is the process of intermolecular recognition and activation, which depends on the actions of ion coordination bond, hydrogen bond, pi-pi stacking action, electrostatic action, hydrophobic action, van der waals force, etc. with the complementation and the interaction degree of the two molecular spatial structures, the distance between the interacting groups is shortened and the acting force is greatly increased, so the interactivity and the complementarity of the ligand and the receptor molecular spatial structures are the main factors of specific combination, i.e. the epitope concept adopted by the invention. The same ligand may correspond to two or more different receptors, and binding of the same ligand to different types of receptors results in different cellular responses. After the ligand is combined with the receptor, related series of physiological activities are initiated, no matter whether the ligand is endogenous or exogenous, after the ligand is combined with the receptor, the ligand and the receptor form a ligand-receptor combination surface or a compound, so that information is transmitted, and through conduction and transduction, rapid cell physiological and biochemical reactions are initiated through amplification, or gene activities are initiated, a series of cascade reactions occur later to coordinate the activities of various tissues, organs and cells, so that the unified whole life makes comprehensive reactions to changeable internal and external environments.
In 2008, Leader et al first proposed ideas classified according to the pharmacological actions of proteins and classified protein drugs into four major categories as follows: protein medicine for treating diseases with the enzyme activity and regulating activity of protein; ② protein drugs with special targeting activity; ③ recombinant protein vaccines; and fourthly, the recombinant protein medicine for diagnosis. Of these, the first and second classes are mainly used in basic protein therapy, and the third and fourth classes emphasize the use of proteins in vaccines and diagnostic applications. After a century of exploration and zigzag development, protein drugs have matured one step by one step and have a great significance in pharmaceutical industry and clinical application. They have important effects on almost all disease fields such as tumors, infections, autoimmune diseases, metabolic genetic diseases, various senile diseases and degenerative diseases, and are becoming important therapeutic, prophylactic and diagnostic drugs in the 21 st century. The wide application of biotechnology with recombinant DNA technology as the core is expected to give protein drugs a wider development space in the future 30 years: the recombinant protein drug will gradually replace the non-recombinant protein; the restructuring and in-vitro and in-vivo modification become conventional; products expressed with mammalian cell systems will predominate; the non-injectable route of administration of protein drugs is receiving increasing attention; biomimic drugs and biosimilar drugs will be most likely. (Zhuxun, functional classification and development trend of protein drugs, volume 5, No.1 of 2.2010, Chinese medicinal biotechnology, Chin Med Biotechnol, February 2010, Vol.5, No. 1).
It has been shown that recognition binding of ligand to the receptor is determined by key amino acid residues of linear or conformational ligand binding epitopes, e.g., phenylalanine (Phe 82), isoleucine (Ile 83) and valine (Val 85) of the FIGV linear ligand binding epitope of the polypeptide 82-85 of boFc γ 2R are key amino acid residues for recognition of binding to the bovine IgG2 receptor, and further, for example, threonine (Thr 142), asparagine (Asn 143), leucine (Leu 144), glycine (Gly 148) and isoleucine (Ile 149) of the TNLSHNGI linear ligand binding epitope of the polypeptide 142-149 of boFc γ RI are key amino acid residues for recognition of binding to the bovine IgG1 receptor; for another example, alanine (Ala 98), glutamic acid (Gln 99), valine (Val 101), valine (Val 102) and asparagine (Asn 103) of the AQRVVN linear ligand binding epitope at positions 98-103 of boFc γ rliii are key amino acid residues for recognition of binding to the bovine IgG1 receptor.
