  2. Transcription (biology) - Wikipedia

    en.wikipedia.org/wiki/Transcription_(biology)

    Production of EGR1 transcription factor proteins, in various types of cells, can be stimulated by growth factors, neurotransmitters, hormones, stress and injury. [27] In the brain, when neurons are activated, EGR1 proteins are up-regulated and they bind to (recruit) the pre-existing TET1 enzymes that are produced in high amounts in neurons.

  3. Transcriptional regulation - Wikipedia

    en.wikipedia.org/wiki/Transcriptional_regulation

    Expression of EGR1 transcription factor proteins, in various types of cells, can be stimulated by growth factors, neurotransmitters, hormones, stress and injury. [24] In the brain, when neurons are activated, EGR1 proteins are up-regulated and they bind to (recruit) the pre-existing TET1 enzymes which are highly expressed in neurons.

  4. General transcription factor - Wikipedia

    en.wikipedia.org/wiki/General_transcription_factor

    GTFs are also intimately involved in the process of gene regulation, and most are required for life. [2] A transcription factor is a protein that binds to specific DNA sequences (enhancer or promoter), either alone or with other proteins in a complex, to control the rate of transcription of genetic information from DNA to messenger RNA by ...

  5. Protein metabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_metabolism

    Protein anabolism is the process by which proteins are formed from amino acids. It relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. Proteins are made from amino acids.

  6. Regulation of gene expression - Wikipedia

    en.wikipedia.org/wiki/Regulation_of_gene_expression

    Up-regulation is a process which occurs within a cell triggered by a signal (originating internal or external to the cell), which results in increased expression of one or more genes and as a result the proteins encoded by those genes. Conversely, down-regulation is a process resulting in decreased gene and corresponding protein expression.

  7. JAK-STAT signaling pathway - Wikipedia

    en.wikipedia.org/wiki/JAK-STAT_signaling_pathway

    The kinase domain is vital for JAK activity, since it allows JAKs to phosphorylate (add phosphate groups to) proteins. There are seven STAT proteins: STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B and STAT6. [1] STAT proteins contain many different domains, each with a different function, of which the most conserved region is the SH2 domain. [2]

  8. Gene expression - Wikipedia

    en.wikipedia.org/wiki/Gene_expression

    All steps in the gene expression process may be modulated (regulated), including the transcription, RNA splicing, translation, and post-translational modification of a protein. Regulation of gene expression gives control over the timing, location, and amount of a given gene product (protein or ncRNA) present in a cell and can have a profound ...

  9. Eukaryotic transcription - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_transcription

    When transcription is arrested by the presence of a lesion in the transcribed strand of a gene, DNA repair proteins are recruited to the stalled RNA polymerase to initiate a process called transcription-coupled repair. [47] Central to this process is the general transcription factor TFIIH that has ATPase activity.
