PF00271Helicase conserved C-terminal domain (Helicase_C)Helicase conserved C-terminal domainThe Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase. Domain
PF00176SNF2-related domain (SNF2-rel_dom)SNF2-related domainThis domain is found in proteins involved in a variety of processes including transcription regulation (e.g., SNF2, STH1, brahma, MOT1), DNA repair (e.g., ERCC6, RAD16, RAD5), DNA recombination (e.g., RAD54), and chromatin unwinding (e.g., ISWI) as w ...This domain is found in proteins involved in a variety of processes including transcription regulation (e.g., SNF2, STH1, brahma, MOT1), DNA repair (e.g., ERCC6, RAD16, RAD5), DNA recombination (e.g., RAD54), and chromatin unwinding (e.g., ISWI) as well as a variety of other proteins with little functional information (e.g., lodestar, ETL1)[1,2,3]. SNF2 functions as the ATPase component of the SNF2/SWI multisubunit complex, which utilises energy derived from ATP hydrolysis to disrupt histone-DNA interactions, resulting in the increased accessibility of DNA to transcription factors.

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].

The structure of this domain revealed that it has a novel fold comprising an antiparallel beta-sheet of seven strands with alpha-helices on one side and random coil on the other [2]. It contains the highly conserved motif WxxxxxPxxGxxxxxxxxxxxxxxxDG. RSC is involved in transcription regulation and nucleosome positioning which controls, particularly, membrane and organelle development genes. The ATP-dependent chromatin remodelling complex SWI/SNF is required for the positive and negative regulation of gene expression of a large number of genes through the regulation of nucleosome remodelling [1].
