Abstract

Histones mediate DNA organisation and plays a dominant role in regulating eukaryotic transcription. The histone-fold consists of a core of three helices, where the long middle helix is flanked at each end by shorter ones. Proteins displaying this structure include the nucleosome core histones, which form octomers composed of two copies of each of the four histones, H2A, H2B, H3 and H4; archaeal histone, which possesses only the core domain part of eukaryotic histone; and the TATA-box binding protein (TBP)-associated factors (TAF), where the histone fold is a common motif for mediating TAF-TAF interactions. TAF proteins include TAF(II)18 and TAF(II)28, which form a heterodimer, TAF(II)42 and TAF(II)62, which form a heterotetramer similar to (H3-H4)2, and the negative cofactor 2 (NC2) alpha and beta chains, which form a heterodimer. The TAF proteins are a component of transcription factor IID (TFIID), along with the TBP protein. TFIID forms part of the pre-initiation complex on core promoter elements required for RNA polymerase II-dependent transcription. The TAF subunits of TFIID mediate transcriptional activation of subsets of eukaryotic genes. The NC2 complex mediates the inhibition of TATA-dependent transcription through interactions with TBP.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 32 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Histone-fold domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 32 hidden Markov models representing the Histone-fold superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
