The binding ability of bovine and human lactoferrins (bLF and hLF; LFs) to a glycyrrhizin (GL)-affinity column and their phosphorylation by casein kinase II (CK-II) in vitro were biochemically investigated. It was found that (i) both bLF and hLF are GL-binding proteins; (ii) purified both proteins function as phosphate acceptors of CK-II; and (iii) this phosphorylation is completely inhibited by two polyphenol-containing anti-oxidant compounds (quercetin and epigallocatechin gallate) at I microm, whereas a glycyrrhetinic acid derivative (oGA) inhibits it at one tenth the concentration of GL. The DNA-binding affinity of hLF was reduced by GL in a dose dependent manner. However, no significant effect of the CK-II-mediated hLF phosphorylation on its DNA-binding affinity was detected. These results suggest that the GL-induced inhibition of the DNA-binding affinity and the CK-II-mediated phosphorylation of hLF may be closely correlated with the anti-inflammatory effect of GL in the human body.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D007781 Lactoferrin An iron-binding protein that was originally characterized as a milk protein. It is widely distributed in secretory fluids and is found in the neutrophilic granules of LEUKOCYTES. The N-terminal part of lactoferrin possesses a serine protease which functions to inactivate the TYPE III SECRETION SYSTEM used by bacteria to export virulence proteins for host cell invasion. Lactotransferrin
D010766 Phosphorylation The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety. Phosphorylations
D011794 Quercetin A flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin. 3,3',4',5,7-Pentahydroxyflavone,Dikvertin

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D004268 DNA-Binding Proteins Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.
