Descriptions Names[Advanced Search]

Any macromolecular complex composed of two or more polypeptide subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleotides, metal ions or other small molecules. A protein complex, distinct from RNA polymerase, that associates with DNA at promoters or at cis-acting regulatory sequences, by direct binding or by interaction with other DNA-binding polypeptides or complexes, and regulates transcription. Large protein complex composed of the RNA polymerase core complex and a variety of other proteins including transcription factor complexes TFIIA, D, E, F, and H which are required for promoter recognition, and the Mediator subcomplex. Catalyzes the synthesis of eukaryotic pre-mRNA. A component of the transcription machinery of RNA Polymerase II. In humans, TFIIA is a heterotrimer composed of an alpha (P35), beta (P19) and gamma subunits (P12). Any constituent part of the nucleoplasm, that part of the nuclear content other than the chromosomes or the nucleolus.
