CC   -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC       DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC       Largest and catalytic component of RNA polymerase II which synthesizes
CC       mRNA precursors and many functional non-coding RNAs. Forms the
CC       polymerase active center together with the second largest subunit. Pol
CC       II is the central component of the basal RNA polymerase II
CC       transcription machinery. It is composed of mobile elements that move
CC       relative to each other. RPB1 is part of the core element with the
CC       central large cleft, the clamp element that moves to open and close the
CC       cleft and the jaws that are thought to grab the incoming DNA template.
CC       At the start of transcription, a single-stranded DNA template strand of
CC       the promoter is positioned within the central active site cleft of Pol
CC       II. A bridging helix emanates from RPB1 and crosses the cleft near the
CC       catalytic site and is thought to promote translocation of Pol II by
CC       acting as a ratchet that moves the RNA-DNA hybrid through the active
CC       site by switching from straight to bent conformations at each step of
CC       nucleotide addition. During transcription elongation, Pol II moves on
CC       the template as the transcript elongates. Elongation is influenced by
CC       the phosphorylation status of the C-terminal domain (CTD) of Pol II
CC       largest subunit (RPB1), which serves as a platform for assembly of
CC       factors that regulate transcription initiation, elongation, termination
CC       and mRNA processing (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC         RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC         COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC         EC=2.7.7.6;
CC   -!- SUBUNIT: Component of the RNA polymerase II (Pol II) complex consisting
CC       of 12 subunits. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- DOMAIN: The C-terminal domain (CTD) serves as a platform for assembly
CC       of factors that regulate transcription initiation, elongation,
CC       termination and mRNA processing. {ECO:0000305}.
CC   -!- PTM: The tandem 7 residues repeats in the C-terminal domain (CTD) can
CC       be highly phosphorylated. The phosphorylation activates Pol II.
CC       Phosphorylation occurs mainly at residues 'Ser-2' and 'Ser-5' of the
CC       heptapeptide repeat. The phosphorylation state is believed to result
CC       from the balanced action of site-specific CTD kinases and phosphatase,
CC       and a 'CTD code' that specifies the position of Pol II within the
CC       transcription cycle has been proposed.
CC   -!- MISCELLANEOUS: The binding of ribonucleoside triphosphate to the RNA
CC       polymerase II transcribing complex probably involves a two-step
CC       mechanism. The initial binding seems to occur at the entry (E) site and
CC       involves a magnesium ion temporarily coordinated by three conserved
CC       aspartate residues of the two largest RNA Pol II subunits. The
CC       ribonucleoside triphosphate is transferred by a rotation to the
CC       nucleotide addition (A) site for pairing with the template DNA. The
CC       catalytic A site involves three conserved aspartate residues of the RNA
CC       Pol II largest subunit which permanently coordinate a second magnesium
CC       ion.
CC   -!- SIMILARITY: Belongs to the RNA polymerase beta' chain family.
CC       {ECO:0000305}.
