Definitions
- Peptide or protein phosphate analysis apparatus Peptide or protein phosphate analysis apparatus, phosphate determination program, and recording medium for the program
- the present invention relates to a peptide or protein analysis device, and more particularly to a device for analyzing the presence or absence of phosphorylation of a peptide or protein, a phosphoric acid discrimination program, and a recording medium for the program.
- Phosphorylation is one of the major post-translational modifications of proteins (more than 100 types such as methylation, acetylation, glycosylation, etc.).
- proteins In eukaryotic cells, many intracellular proteins are phosphorylated. ing. Protein phosphorylation occurs instantaneously and reversibly, and is one of the basic processes of signal transduction as a major intracellular activity control mechanism.
- phosphorylation means that phosphoric acid binds to a specific amino acid in an amino acid constituting a peptide or protein.
- dephosphorylation means that phosphoric acid is cleaved from amino acid bound with phosphoric acid.
- Phosphorylase protein kinase
- phosphatase protein phosphatase
- phosphorylase or phosphatase functions as a central regulator in intracellular signal transduction and cell cycle.
- the state of protein phosphate changes with various stresses and diseases. Sexual abnormalities are thought to be involved in many chronic diseases and carcinogenesis. Therefore, it is doubtful that the elucidation of the phosphorylation / dephosphorylation mechanism is important for the elucidation of physiological regulation mechanisms, new drug discovery, and analysis of disease pathologies.
- These enzymes have a function of binding or cleaving a phosphate group to a protein. That is, the phosphate enzyme acts on an amino acid at a specific site of a protein, and functions to change its function by binding phosphate to the residue of the amino acid.
- phosphatase changes the function of a protein by targeting the amino acid to which a phosphate is bound at a specific site in the protein, cleaving the bond between the amino acid and the phosphate, and bringing the amino acid into the original residue. I am working.
- Phosphorylation of a protein by a phosphorylase selectively occurs at a specific amino acid.
- phosphate binds mainly to the residues of three types of amino acids: threonine (T: Threonine), serine (S: Serine), and tyrosine (Y: Tyrosine). It occurs by doing.
- Ca 2+ Z calmodulin-dependent protein kinase (phosphate enzyme), which is one of the major players in intracellular Ca 2+ signaling in the central nervous system, its own threonine residue is phosphate.
- Ca 2+ / calmodulin-independent activity occurs, and other basic proteins can be phosphorylated. Therefore, discriminating whether or not Ca 2+ / calmodulin-dependent protein kinase is phosphated is an important indicator when monitoring the state of central nervous system activity.
- Patent Document 1 discloses a technique for detecting the presence or absence of a peptide phosphate using a mass spectrometer.
- Patent Document 2 discloses a technique for identifying a phosphate protein by two-dimensional electrophoresis.
- Non-Patent Document 1 discloses a technique for detecting a phosphorylated protein by Western blot using an antibody specific for phosphorylated amino acid.
- Non-Patent Document 2 discloses a technique for quantifying peptides or proteins by measuring absorption in the ultraviolet region (for example, 280 nm) with a spectrophotometer as a method for analyzing peptides or proteins. RU

- Non-Patent Document 2 Biochemistry Experiment Course 1 Protein Chemistry II “2. Protein Determination”, Tokyo Kagaku Dojin, 1981, p23- 28
- Patent Document 1 when detecting that a peptide contains phosphoric acid by a mass spectrometer, a strong acid such as fluoracetic acid is used as a pretreatment for 8 hours to 24 hours. It is necessary to react.
- fluoracetic acid is a strong acid and is a substance that corrodes tissues in the body, so care must be taken to avoid contact with the human body.
- mass spectrometers are expensive and are handled by an assigned operator. In this way, it took a long time to measure one sample, and it was impossible to have an operator who could not handle a large amount of processing.
- the technique disclosed in Patent Document 2 requires the following steps in order to detect whether the target sample is phosphated.
- the sample is dephosphorylated with a dephosphorylating enzyme.
- two-dimensional electrophoresis is performed using the sample before and after the reaction.
- the third step after two-dimensional electrophoresis, it is compared whether the target sample is electrophoresed at different positions before and after the enzyme reaction. Through these steps, the presence or absence of phosphorylation is detected.
- the protein electrophoresis pattern changes due to changes in sample conditions and delicate electrophoresis conditions. PH, voltage 'current and buffer pH are always required to be performed under the same conditions, requiring skill in operation, and many samples in one two-dimensional electrophoresis. The problem of being unable to flow has occurred!
- Non-Patent Document 1 a sample containing the target protein is subjected to sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis and separated on the gel for each molecular weight of the protein. .
- SDS sodium dodecyl sulfate
- the separated gel is transferred to a membrane such as -trocellulose by a charging method, and then the antigen-antibody reaction is developed on the transferred membrane.
- the specificity and sensitivity of the antibody that reacts with phosphorylated amino acids are the key points.
- Non-Patent Document 2 focuses on the fact that the maximum absorption of tryptophan, tyrosine, and phenylalanine, which are amino acids constituting peptides or proteins, is in the ultraviolet region (near 280 nm). Is the method.
