The process of introducing a phosphate group on to an amino acid residue in the C-terminal domain of RNA polymerase II. Typically, this occurs during the transcription cycle and results in production of an RNA polymerase II enzyme where the carboxy-terminal domain (CTD) of the largest subunit is extensively phosphorylated, often referred to as hyperphosphorylated or the II(0) form. Specific types of phosphorylation within the CTD are usually associated with specific regions of genes, though there are exceptions. The phosphorylation state regulates the association of specific complexes such as the capping enzyme or 3'-RNA processing machinery to the elongating RNA polymerase complex. Any process that activates or increases the frequency, rate or extent of translation initiation in response to stress by the phosphorylation of eIF2 alpha. The chemical reactions and pathways involving the phosphate group, the anion or salt of any phosphoric acid. The phosphorylation of peptidyl-cysteine to form peptidyl-S-phospho-L-cysteine. The initiation of the activity of the inactive enzyme MAP kinase by phosphorylation by a MAPKK. The initiation of the activity of the inactive enzyme MAP kinase kinase by phosphorylation by a MAPKKK. The phosphorylation by a protein of one or more of its own amino acid residues, or residues on an identical protein. The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine. The posttranslational phosphorylation of peptidyl-threonine to form peptidyl-O-phospho-L-threonine. The posttranslational phosphorylation of peptidyl-histidine to form peptidyl-1'-phospho-L-histidine (otherwise known as tau-phosphohistidine, tele-phosphohistidine) or peptidyl-3'-phospho-L-histidine (otherwise known as pi-phosphohistidine, pros-phosphohistidine). The transfer of one or more phosphate groups to an actin molecule. Upregulation of the activity of a caspase, any of a group of cysteine proteases involved in apoptosis, by the addition of a phosphate group. The process of introducing a phosphate group into an I-kappaB protein. The modification of histones by addition of phosphate groups. The posttranslational phosphorylation of peptidyl-aspartic acid. The posttranslational phosphorylation of peptidyl-tyrosine to form peptidyl-O4'-phospho-L-tyrosine. The posttranslational phosphorylation of peptidyl-arginine to form omega-N-phospho-L-arginine. The process of introducing a phosphate group into a JUN protein. The process that inhibits the signaling function of a G-protein coupled receptor by addition of a phosphate group to its third intracellular loop consensus site. The widespread phosphorylation of various molecules, triggering many downstream processes, that occurs in response to the detection of DNA damage. The process of introducing a phosphate group on to a common-partner SMAD protein. A common partner SMAD protein binds to pathway-restricted SMAD proteins forming a complex that translocates to the nucleus. The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide. Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein. Any process that stops, prevents or decreases the rate of addition of phosphate groups to amino acids within a protein. Any process that modulates the frequency, rate or extent of addition of phosphate groups into an amino acid in a protein. The process of introducing a phosphate group on to a protein. The process of introducing a phosphate group on to a pathway restricted SMAD protein. A pathway restricted SMAD protein is an effector protein that acts directly downstream of the transforming growth factor family receptor. The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). The covalent alteration of one or more amino acids occurring in a protein after the protein has been completely translated and released from the ribosome.
