CC   -!- FUNCTION: DNA-dependent RNA polymerase catalyzes the transcription of
CC       DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC       Component of RNA polymerase II which synthesizes mRNA precursors and
CC       many functional non-coding RNAs. Pol II is the central component of the
CC       basal RNA polymerase II transcription machinery. It is composed of
CC       mobile elements that move relative to each other. RPB7 is part of a
CC       subcomplex with RPB4 that binds to a pocket formed by RPB1, RPB2 and
CC       RPB6 at the base of the clamp element. The RBP4-RPB7 subcomplex seems
CC       to lock the clamp via RPB7 in the closed conformation thus preventing
CC       double-stranded DNA to enter the active site cleft. The RPB4-RPB7
CC       subcomplex binds single-stranded DNA and RNA (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Component of the RNA polymerase II (Pol II) complex consisting
CC       of 12 subunits. RPB4 and RPB7 form a subcomplex that protrudes from the
CC       10-subunit Pol II core complex.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the eukaryotic RPB7/RPC8 RNA polymerase subunit
CC       family. {ECO:0000305}.
