Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

11 GO

Gene Ontology (GO)

11
  • GO:0032993 A macromolecular complex containing both protein and DNA molecules.
  • GO:0001216 A DNA-binding transcription factor activity that activates or increases transcription of specific gene sets.
  • GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons.
  • GO:0043565 Binding to 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:0000976 Binding to a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon.
  • GO:0045893 Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0009372 The cell-cell signaling process in which single-celled organisms carry out coordinated responses by monitoring their own population density, and often also that of other microbes, by producing small, diffusible, signal molecules, detecting the concentration of these molecules, and triggering a signal transduction pathway when a certain threshold is reached. Quorum sensing can occur amongst microbial communities in the environment or within host organisms.
  • GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
  • GO:0060310 Any process that modulates the rate, frequency or extent of elastin catabolism, the chemical reactions and pathways resulting in the breakdown of elastin.
  • GO:0010468 Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).
  • GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
