This domain is found in ATP-dependent helicase CHD1/2 from animals and its orthologues hrp1/3 (Hrp1/3) from Schizosaccharomyces pombe. CHD1 is an ATP-dependent chromatin-remodeling factor which functions as substrate recognition component of the transcription regulatory histone acetylation (HAT) complex SAGA. It regulates polymerase II transcription and it is also required for efficient transcription by RNA polymerase I, and more specifically the polymerase I transcription termination step [1-3]. Hrp1/3 are involved in heterochromatin silencing [4,5]. This domain is predicted to adopt an HTH structure and is often found C-terminal to Pfam:PF18196.

This domain can be found in chromodomain helicase DNA-binding protein 1 (Chd1) present in Saccharomyces cerevisiae. Cdh1 proteins have been associated with the efficient assembly and spacing of nucleosomes. The domain consists of four helices, alpha helix 1-4, and can be divided into regions SANT, HL1 and the beta-linker. The HL1 region comprises of some 40 residues specific to budding yeast that are unlikely to form such a prominent feature or perform a conserved function in other species. The domain itself forms part of the DNA-binding domain. Basic residues on the alpha-1 helix are thought to be important for DNA interaction [1].
The 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.
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 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.

CENP-T is a family of vertebral kinetochore proteins that associates directly with CENP-W. 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].
