 15-103 1.71e-56

histone-fold domain found in histone H2A and similar proteins; Histone H2A is the core component of the nucleosome, which wraps and compacts DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling. The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.

second histone-fold domain found in son of sevenless homolog 1 (SOS-1) and similar proteins; SOS-1 is a guanine nucleotide exchange factor for Ras that binds to GRB2. It promotes the exchange of Ras-bound GDP by GTP. It is a catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac, by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity. SOS-1 contains tandem histone folds at the N-terminal region. The model corresponds to the second repeat.

 17-97 7.53e-13

histone-fold domain found in ankyrin repeat and BTB/POZ domain-containing protein 2 (ABTB2) and similar proteins; ABTB2, also called Bood POZ containing gene type 2 (BPOZ-2), is a scaffold protein that controls the degradation of many biological proteins ranging from embryonic development to tumor progression. It may be involved in the initiation of hepatocyte growth. It inhibits the aggregation of alpha-synuclein, which has implications for Parkinson's disease. ABTB2 functions as an adaptor protein for the E3 ubiquitin ligase scaffold protein Cullin-3. It directly binds to eukaryotic elongation factor 1A1 (eEF1A1) to promote eEF1A1 ubiquitylation and degradation and prevent translation. It is also involved in the growth suppressive effect of the phosphatase and tensin homolog (PTEN). This subfamily also includes BTB/POZ domain-containing protein 11 (BTBD11), also called ankyrin repeat and BTB/POZ domain-containing protein BTBD11. It is a BTB-domain-containing Kelch-like protein with unknown function.

histone-fold domain found in Dr1-associated protein 1 (DRAP1) and similar proteins; DRAP1, also called Dr1-associated corepressor or negative cofactor 2-alpha (NC2-alpha), acts as a corepressor for Dr1 (down-regulator of transcription 1)-mediated repression of transcription. It forms a heterodimer with Dr1. The association of the Dr1/DRAP1 heterodimer with TBP results in a functional repression of both activated and basal transcription of class II genes. DRAP1 can bind to DNA on its own. It also binds TATA-binding protein-associated factor 172 (BTAF1).

 25-88 5.15e-04

histone fold domain (HFD) superfamily; The histone fold domain (HFD) is a structurally conserved interaction motif involved in heterodimerization of the core histones and their assembly into the nucleosome octamer. Histone fold heterodimers play crucial roles in gene regulation. The minimal HFD consists of three alpha helices connected by two short, unstructured loops. The HFD is found in core histones, TATA box-binding protein-associated factors (TAFs), and many other transcription factors. HFD plays a role in the nucleosomal core particle by conserving histone interactions; these contain more than one HFD. The structure of the nucleosome core particle has two modes that have the largest interaction surfaces, and these are the H3-H4 and H2A-H2B heterodimer interactions. Several TAFs interact via histone-fold (HF) motifs. Five HF-containing TAF pairs have been described in transcription factor II D (TFIID): TAF6-TAF9, TAF4-TAF12, TAF11-TAF13, TAF8-TAF10 and TAF3-TAF10.

 23-96 4.94e-03

histone-fold domain found in Schizosaccharomyces pombe DNA polymerase epsilon subunit C (Dpb3) and similar proteins; Schizosaccharomyces pombe Dpb3 is an accessory component of the DNA polymerase epsilon (DNA polymerase II) that is a heterotetramer consisting of cdc20/Pol2, Dpb2, Dpb3, and Dpb4, and participates in chromosomal DNA replication. Dpb3 is required during synthesis of the leading and lagging DNA strands at the replication fork and binds at/or near replication origins and moves along DNA with the replication fork. It has 3'-5' proofreading exonuclease activity that correct errors arising during DNA replication. It is also involved in DNA synthesis during DNA repair. The Dpb3-Dpb4 dimer associates with histone deacetylases, chromatin remodelers, and histones and plays a crucial role in the inheritance of histone hypoacetylation and H3K9 methylation in heterochromatin. The Dpb3-Dpb4 dimer is also required for the recruitment of sir2 to heterochromatin.
