CCAAT-Binding Factor: A heterotrimeric DNA-binding protein that binds to CCAAT motifs in the promoters of eukaryotic genes. It is composed of three subunits: A, B and C.CCAAT-Enhancer-Binding Proteins: A class of proteins that were originally identified by their ability to bind the DNA sequence CCAAT. The typical CCAAT-enhancer binding protein forms dimers and consists of an activation domain, a DNA-binding basic region, and a leucine-rich dimerization domain (LEUCINE ZIPPERS). CCAAT-BINDING FACTOR is structurally distinct type of CCAAT-enhancer binding protein consisting of a trimer of three different subunits.Core Binding Factors: Heterodimeric transcription factors containing a DNA-binding alpha subunits, (CORE BINDING FACTOR ALPHA SUBUNITS), along with a non-DNA-binding beta subunits, CORE BINDING FACTOR BETA SUBUNIT. Core Binding Factor regulates GENETIC TRANSCRIPTION of a variety of GENES involved primarily in CELL DIFFERENTIATION and CELL CYCLE progression.NFI Transcription Factors: Transcription factors that were originally identified as site-specific DNA-binding proteins essential for DNA REPLICATION by ADENOVIRUSES. They play important roles in MAMMARY GLAND function and development.Y-Box-Binding Protein 1: Y-box-binding protein 1 was originally identified as a DNA-binding protein that interacts with Y-box PROMOTER REGIONS of MHC CLASS II GENES. It is a highly conserved transcription factor that regulates expression of a wide variety of GENES.DNA-Binding Proteins: Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.Transcription Factors: Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.Base Sequence: The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.Promoter Regions, Genetic: DNA sequences which are recognized (directly or indirectly) and bound by a DNA-dependent RNA polymerase during the initiation of transcription. Highly conserved sequences within the promoter include the Pribnow box in bacteria and the TATA BOX in eukaryotes.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Core Binding Factor beta Subunit: A non-DNA binding transcription factor that is a subunit of core binding factor. It forms heterodimeric complexes with CORE BINDING FACTOR ALPHA SUBUNITS, and regulates GENETIC TRANSCRIPTION of a variety of GENES involved primarily in CELL DIFFERENTIATION and CELL CYCLE progression.Pol1 Transcription Initiation Complex Proteins: Factors that form a preinitiation complex at promoters that are specifically transcribed by RNA POLYMERASE I.Core Binding Factor alpha Subunits: A family of transcription factors that bind to the cofactor CORE BINDING FACTOR BETA SUBUNIT to form core binding factor. Family members contain a highly conserved DNA-binding domain known as the runt domain. They can act as both activators and repressors of expression of GENES involved in CELL DIFFERENTIATION and CELL CYCLE progression.Telomeric Repeat Binding Protein 1: A ubiquitously expressed telomere-binding protein that is present at TELOMERES throughout the CELL CYCLE. It is a suppressor of telomere elongation and may be involved in stabilization of telomere length. It is structurally different from TELOMERIC REPEAT BINDING PROTEIN 2 in that it contains acidic N-terminal amino acid residues.G-Box Binding Factors: A family of transcription factors found primarily in PLANTS that bind to the G-box DNA sequence CACGTG or to a consensus sequence CANNTG.CCAAT-Enhancer-Binding Protein-beta: A CCAAT-enhancer-binding protein found in LIVER; INTESTINES; LUNG and ADIPOSE TISSUE. It is an important mediator of INTERLEUKIN-6 signaling.Transcription, Genetic: The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION.Core Binding Factor Alpha 2 Subunit: A transcription factor that dimerizes with the cofactor CORE BINDING FACTOR BETA SUBUNIT to form core binding factor. It contains a highly conserved DNA-binding domain known as the runt domain. Runx1 is frequently mutated in human LEUKEMIAS.
