The SAGA coactivator complex acts on the whole transcribed genome and is required for RNA polymerase II transcription [Yeast cells]

The SAGA co-activator complex contains distinct chromatin-modifying activities and is recruited by DNA-bound activators to regulate the expression of a subset of genesSAGA共激活因子复合物（SAGA co-activator complex）具备独特的染色质修饰活性，可被DNA结合型激活因子招募，以调控特定基因子集的表达。
