Asymmetric Unit(hide GO term definitions)
Chain A   (REG6_PYRHO | O59188)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0043565    sequence-specific DNA binding    Interacting selectively and non-covalently with DNA of a specific nucleotide composition, e.g. GC-rich DNA binding, or with a specific sequence motif or type of DNA e.g. promotor binding or rDNA binding.
    GO:0003700    transcription factor activity, sequence-specific DNA binding    Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
biological process
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
