Protein phosphorylation is a reversible post-translational modification of proteins. In eukaryotes, protein phosphorylation functions in cell signaling, gene expression, and differentiation. It is also involved in DNA replication during the cell cycle, and the mechanisms that cope with stress-induced replication blocks. See more Protein phosphorylation is a reversible post-translational modification of proteins in which an amino acid residue is phosphorylated by a protein kinase by the addition of a covalently bound phosphate group. … See more Reversible phosphorylation of proteins is abundant in both prokaryotic and even more so in eukaryotic organisms. For instance, in bacteria … See more Within a protein, phosphorylation can occur on several amino acids. Phosphorylation on serine is thought to be the most common, … See more There are thousands of distinct phosphorylation sites in a given cell since: 1. There are thousands of different kinds of proteins in any particular cell (such as a lymphocyte). 2. It is estimated that 1/10 to 1/2 of proteins are phosphorylated (in some cellular state). See more In 1906, Phoebus Levene at the Rockefeller Institute for Medical Research identified phosphate in the protein vitellin (phosvitin), and by 1933 had detected phosphoserine in See more Phosphorylation introduces a charged and hydrophilic group in the side chain of amino acids, possibly changing a protein's structure by altering … See more While tyrosine phosphorylation is found in relatively low abundance, it is well studied due to the ease of purification of phosphotyrosine using antibodies.
