Descriptions Names[Advanced Search]

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. 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 complex which is part of both the general transcription factor TFIIH and the nucleotide-excision repair factor 3 complex. It is composed of the tightly associated 5 subunit core TFIIH subcomplex plus one additional, more loosely associated subunit. The subunits are well conserved from yeast to humans. In S. cerevisiae, the 5-subunit core is composed of Rad3, Tfb1, Tfb2, Ssl1, Tfb4 and the loosely associated subunit is Ssl2p (also called Rad25). In humans, the 5 subunit core is composed of ERCC2, p62, p55, p44, p34 and the loosely associated subunit is XPB. Any constituent part of the nucleus, a membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. 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. The SSL2-core TFIIH complex when it is part of the general transcription factor TFIIH. It is composed of the tightly associated five subunit core TFIIH subcomplex plus one additional, less tighly associated subunit. The subunits are well conserved from yeast to humans. In S. cerevisiae, the 5-subunit core is composed of Rad3, Tfb1, Tfb2, Ssl1, Tfb4 and the loosely associated subunit is Ssl2p (also called Rad25). In humans, the 5 subunit core is composed of ERCC2, p62, p55, p44, p34 and the loosely associated subunit is XPB. That part of the nuclear content other than the chromosomes or the nucleolus. The core TFIIH complex when it is part of the general transcription factor TFIIH. In S. cerevisiae, it is composed of Rad3p, Tfb1p, Tfb2p, Ssl1p and Tfb4p. In humans, it is composed of ERCC2, p62, p55, p44, p34. Any constituent part of the nucleoplasm, that part of the nuclear content other than the chromosomes or the nucleolus. A complex that contains kinase activity directed towards the C-terminal Domain (CTD) of the largest subunit of RNA polymerase II and is essential for initiation at RNA polymerase II promoters in vitro. In S. cerevisiae, it is composed of the 5-subunit core (Rad3p, Tfb1p, Tfb2p, Ssl1p and Tfb4p), Ssl2p, and TFIIK (Kin28p, Ccl1p, and Tfb3p). All of the subunits have equivalents in humans: the 5 subunit core is composed of ERCC2, p62, p55, p44, p34; the equivalent of the TFIIK subcomplex is composed of MO15, Mat1, and a cyclin; the human equivalent of Ssl2p is XPB.
