Activator of basal transcription 1

ABT1, activator of basal transcription 1, Esf2, Esf2p, TATA-binding protein-binding protein
Basal transcription of genes by RNA polymerase II requires the interaction of TATA-binding protein (TBP) with the core region of class II promoters. Studies in mouse suggest that the protein encoded by this gene likely activates basal transcription from class II promoters by interaction with TBP and the class II promoter DNA.

[Cutting propagation of Periploca forrestii and dynamic analyses of physiological and biochemical characteristitics related to adventitious roots formation].
Yang et al., Chongqing, China. In Zhong Yao Cai, 2011
METHODS: Cuttings propagation characters of Periploca forrestii were investigated and compared with different concentration treatments of indolebutyric acid (IBA), Rooting Powder No. 1 (ABT1) and naphthylacetic acid (NAA).
Mouse Dfa is a repressor of TATA-box promoters and interacts with the Abt1 activator of basal transcription.
Varshavsky et al., Pasadena, United States. In J Biol Chem, 2010
Furthermore, Dfa(A) was present in the interchromatin granule clusters and was also found to bind to the Ggnbp1 gametogenetin-binding protein-1 and to the Abt1 activator of basal transcription that interacts with the TATA-binding protein.
Biochemical and genetic evidence for a role of IGHMBP2 in the translational machinery.
Mourelatos et al., Philadelphia, United States. In Hum Mol Genet, 2009
We find that a 166 kb BAC transgene derived from CAST/EiJ mice and containing tRNA genes and activator of basal transcription 1 (Abt1), a protein-coding gene that is required for ribosome biogenesis, contains the genetic modifier responsible for motor neuron rescue.
The nucleolar protein Esf2 interacts directly with the DExD/H box RNA helicase, Dbp8, to stimulate ATP hydrolysis.
Baserga et al., New Haven, United States. In Nucleic Acids Res, 2005
Identification of Esf2, a nucleolar putative RNA binding protein, as a binding partner for Dbp8, and show that it enhances Dbp8 ATPase activity by decreasing the K(M) for ATP.
Esf2p, a U3-associated factor required for small-subunit processome assembly and compaction.
Lafontaine et al., Charleroi, Belgium. In Mol Cell Biol, 2005
Esf2p is the Saccharomyces cerevisiae homolog of mouse ABT1, a protein previously identified as a putative partner of the TATA-element binding protein.
ABT1-associated protein (ABTAP), a novel nuclear protein conserved from yeast to mammals, represses transcriptional activation by ABT1.
Yamashita et al., Tokyo, Japan. In J Cell Biochem, 2004
We recently identified a novel nuclear protein, activator of basal transcription 1 (ABT1), which binds TBP and DNA, and enhances Pol II-directed basal transcription.
[Community types, phenology and propagation characteristics of Taxus mairei in north Guangdong].
Deng et al., Guangzhou, China. In Ying Yong Sheng Tai Xue Bao, 2002
The effect of cuttage was better by taking mature annual twig and pretreatment by ABT1(100 mg.L-1) from October to November every year, and the rooting rate could be up to 95%.
A novel TATA-binding protein-binding protein, ABT1, activates basal transcription and has a yeast homolog that is essential for growth.
Muramatsu et al., Kisarazu, Japan. In Mol Cell Biol, 2000
Identification of a novel mouse nuclear protein termed activator of basal transcription 1 (mABT1) that associates with the TATA-binding protein (TBP) and enhances basal transcription activity of class II promoters is described.
