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. Any complex formed of proteins that act in nucleotide-excision repair. One of several protein complexes involved in nucleotide-excision repair; possesses endodeoxynuclease and DNA helicase activities. In S. cerevisiae, it is composed of Rad2p and the core TFIIH-Ssl2p complex (Core TFIIH is composed of Rad3p, Tfb1p, Tfb2p, Ssl1p, and Tfb4p. Note that Ssl2p is also called Rad25p). Any constituent part of the nucleus, a membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. The SSL2-core TFIIH complex when it is part of the nucleotide-excision repair factor 3 (NEF3). It is composed of the tightly associated 5 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.
