POU Domain Factors: A family of transcription factors characterized by the presence of a bipartite DNA-binding domain known as the POU domain. The POU domain contains two subdomains, a POU-specific domain and a POU-homeodomain. The POU domain was originally identified as a region of approximately 150 amino acids shared between the Pit-1, Oct-1, Oct-2, and Unc-86 transcription factors.Octamer Transcription Factor-6: An octamer transcription factor that plays an important role in the MYELIN SHEATH development by SCHWANN CELLS.Transcription Factor Brn-3: A family of mammalian POU domain factors that are expressed predominately in NEURONS.Transcription Factors: Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.Octamer Transcription Factor-1: A ubiquitously expressed octamer transcription factor that regulates GENETIC TRANSCRIPTION of SMALL NUCLEAR RNA; IMMUNOGLOBULIN GENES; and HISTONE H2B genes.Host Cell Factor C1: A cellular transcriptional coactivator that was originally identified by its requirement for the stable assembly IMMEDIATE-EARLY PROTEINS of the HERPES SIMPLEX VIRUS. It is a nuclear protein that is a transcriptional coactivator for a number of transcription factors including VP16 PROTEIN; GA-BINDING PROTEIN; EARLY GROWTH RESPONSE PROTEIN 2; and E2F4 TRANSCRIPTION FACTOR. It also interacts with and stabilizes HERPES SIMPLEX VIRUS PROTEIN VMW65 and helps regulate GENETIC TRANSCRIPTION of IMMEDIATE-EARLY GENES in HERPES SIMPLEX VIRUS.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 Factor Brn-3B: A POU domain factor that represses GENETIC TRANSCRIPTION of GENES encoding NEUROFILAMENT PROTEINS, alpha internexin, and SYNAPTOSOMAL-ASSOCIATED PROTEIN 25.Transcription Factor Brn-3C: A POU domain factor that activates neuronal cell GENETIC TRANSCRIPTION of GENES encoding NEUROFILAMENT PROTEINS, alpha internexin, and SYNAPTOSOMAL-ASSOCIATED PROTEIN 25. Mutations in the Brn-3c gene have been associated with DEAFNESS.Base Sequence: The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.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.Binding Sites: The parts of a macromolecule that directly participate in its specific combination with another molecule.Octamer Transcription Factor-2: An octamer transcription factor expressed primarily in B-LYMPHOCYTES and the developing CENTRAL NERVOUS SYSTEM that regulates GENETIC TRANSCRIPTION of IMMUNOGLOBULIN GENES.Transcription Factor Pit-1: A POU domain factor that regulates expression of GROWTH HORMONE; PROLACTIN; and THYROTROPIN-BETA in the ANTERIOR PITUITARY GLAND.Gene Expression Regulation, Developmental: Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action during the developmental stages of an organism.Transcription Factor Brn-3A: A POU domain factor that activates GENETIC TRANSCRIPTION of GENES encoding NEUROFILAMENT PROTEINS; alpha internexin; SYNAPTOSOMAL-ASSOCIATED PROTEIN 25; and BCL-2 PROTO-ONCOGENE PROTEINS.Octamer Transcription Factor-3: An octamer transcription factor that is expressed primarily in totipotent embryonic STEM CELLS and GERM CELLS and is down-regulated during CELL DIFFERENTIATION.Herpes Simplex Virus Protein Vmw65: Trans-acting protein that combines with host factors to induce immediate early gene transcription in herpes simplex virus.
