Resumo de Recurso

different TFs
  1. Bascal Transcription
    1. associated with TATA binding protein or TBP
    2. Other transcription factors
      1. control expression of genes in different locations at different times
      2. TFs that bind at the promoter and enhancers drive differential gene expression
        1. enhancers bind to TFs that possitively regulate transcription
          1. silencers bind repressors (negative effect)
        2. TFa binds to the TATA and helps polymerase bind at the start
          1. other TFs must bend the DNA to get to the RNA polymerase
            1. b and c are bending proteins
              1. when b bends d binds to polymerase
                1. when c bends e binds to polymerase
                  1. both b and c can't bend
                  2. d and e activate rna
                    1. look at sheet with shapes
