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].

This entry represents the N-terminal domain of SWI/SNF and RSC complexes subunit Ssr4 from S. pombe, a essential member of the chromatin structure remodelling complex (RSC) and the SWI/SNF complex [1,2]. 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].
This family includes the SWIB domain and the MDM2 domain [1]. The p53-associated protein (MDM2) is an inhibitor of the p53 tumour suppressor gene binding the transactivation domain and down regulating the ability of p53 to activate transcription. Thi ...
This family includes the SWIB domain and the MDM2 domain [1]. The p53-associated protein (MDM2) is an inhibitor of the p53 tumour suppressor gene binding the transactivation domain and down regulating the ability of p53 to activate transcription. This family contains the p53 binding domain of MDM2 [2].
This SWIRM domain is a small alpha-helical domain of about 85 amino acid residues found in chromosomal proteins. It contains a helix-turn helix motif and binds to DNA [1].
