 18-105 4.07e-46

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; ...
 28-100 9.04e-12

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.

histone-fold domain found in ankyrin repeat and BTB/POZ domain-containing protein 2 (ABTB2) ...
 18-97 1.26e-11

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.
