The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].

Three transcription-elongation factors Spt4, Spt5, and Spt6 are conserved among eukaryotes and are essential for transcription via the modulation of chromatin structure. Spt4 and Spt5 are tightly associated in a complex, while the physical association of the Spt4-Spt5 complex with Spt6 is considerably weaker. It has been demonstrated that Spt4, Spt5, and Spt6 play roles in transcription elongation in both yeast and humans including a role in activation by Tat. It is known that Spt4, Spt5, and Spt6 are general transcription-elongation factors, controlling transcription both positively and negatively in important regulatory and developmental roles [1]. RpoE2 is one of 13 subunits in the archaeal RNA polymerase. These proteins contain a C4-type zinc finger, and the structure has been solved in [3]. The structure reveals that Spt4-Spt5 binding is governed by an acid-dipole interaction between Spt5 and Spt4, and the complex binds to and travels along the elongating RNA polymerase. The Spt4-Spt5 complex is likely to be an ancient, core component of the transcription elongation machinery.

This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III.

This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at least one of the subunits contacted by the transcription factor TIF-IA [2]. The N terminus of Rpb7p/Rpc25p/MJ0397 has a SHS2 domain that is involved in protein-protein interaction [3].
Domain
PF00575S1 RNA binding domain (S1)S1 RNA binding domainThe S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure.Domain
