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 that phosphorylates amino acid residues of RNA polymerase II C-terminal domain repeats; phosphorylation occurs mainly on Ser2 and Ser5. The 5 subunit core of TFIIH that has tightly associated subunits and is found in both the general transcription factor holo-TFIIH and in the nucleotide-excision repair factor 3 complex. In S. cerevisiae, it is composed of Rad3, Tfb1, Tfb2, Ssl1, Tfb4. In humans, it is composed of XPD, p62, p55, p44, p34. The core TFIIH complex when it is part of the nucleotide-excision repair factor 3 (NEF3). In S. cerevisiae, it is composed of Rad3p, Tfb1p, Tfb2p, Ssl1p, and Tfb4p. In humans, it is composed of ERCC2, p62, p55, p44, p34. 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. 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.
