Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (HSF_KLULA | P22121)
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:0032007    negative regulation of TOR signaling    Any process that stops, prevents, or reduces the frequency, rate or extent of TOR signaling.
    GO:0006357    regulation of transcription from RNA polymerase II promoter    Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0009408    response to heat    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a heat stimulus, a temperature stimulus above the optimal temperature for that organism.
    GO:0030474    spindle pole body duplication    Construction of a new spindle pole body.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
