proteins that recognize and bind to specific DNA sequences associated with a particular gene, thereby affecting the expression of that gene.
Proteins that assemble on a eukaryotic chromosome, allowing RNA polymerase II to perform transcription.
A group of regulatory proteins that are required for transcription in eukaryotes. Transcription factors bind to the promoter region of a gene and facilitate transcription by RNA polymerase.
Specific proteins which allow DNA recognition by RNA polymerases in eukaryotes.
in molecular biology, a transcription factor is a protein that binds DNA at a specific promoter or enhancer region or site, where it regulates transcription. Transcription factors can be selectively activated or deactivated by other proteins, often as the final step in signal transduction.
Proteins that bind to DNA and help initiate gene transcription. Transcription factors are often important elements of signal transduction pathways.
Proteins in eukaryotes that regulate the transcription of other genes by binding to regulatory sequences of the gene, interaction with one another and with the RNA polymerase.
Specialized proteins that bind to specific sites on DNA and turn on or turn off the expression of different sets of genes.
The class of proteins which bind to DNA and promote or inhibit the initiation of transcription.
Proteins which bind "promoter" regions of DNA upstream of the sequences which encode mRNA, thereby leading to assembly of an RNA polymerase and transcription of the gene.
