Allosteric activation of rna polymerase i - Chapter 18- Regulation of Gene Expression Flashcards
Eukaryotic RNA polymerase II (Pol II) requires five protein cofactors for promoter recognition and initiation of transcription. The factor TFIIB is implicated in start site selection and stabilization of the initial transcript.
The prokaryotic RNA polymerase is a multiple-subunit protein of ~480kD. *constitutive or basal level transcription. allosteric activation of rna polymerase.

Explain the function of RNA polymerase. interaction between a protein and its allosteric effector results in the activation of gene expression.
RNA pol II associates with a large number of two SPXX motifs in the CTD of RNA polymerase in the recruitment and allosteric activation of mammalian
