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. 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 modulates the frequency, rate or extent of cellular DNA-dependent transcription. The synthesis of RNA from a DNA template by RNA polymerase II (Pol II), originating at a Pol II-specific promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs). Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter. The process of introducing a phosphate group onto a serine residue at position 2 within the heptapeptide repeat (YSPTSPS) of the C-terminal domain of RNA polymerase II. Typically, phosphorylation of serine 2 (Ser2) occurs subsequent to phosphorylation of serine 5 and is thus seen in the middle and 3' ends of genes. In vivo, Ser5 phosphorylation is primarily performed by CTDK-I in S. cerevisiae or CDK9 in metazoans. The process of introducing a phosphate group onto a serine residue at position 5 within the heptapeptide repeat (YSPTSPS) of the C-terminal domain of RNA polymerase II. Typically, phosphorylation of serine 5 (Ser5) occurs near the 5' ends of genes. It is generally still observed in the middle of genes, overlapping with phosphorylation of serine 2, but is generally not present at the 3' ends of genes. In vivo, Ser5 phosphorylation occurs primarily through the action of TFIIH (KIN28 in S. cerevisiae, CKD7 in metazoans). The process of introducing a phosphate group on to a protein. 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.
