DNA-binding protein that recognizes sites within both the enhancer and the promoter of rRNA transcription, as well as upstream of many genes transcribed by RNA polymerase II. It is essential for cell growth. May stimulate or inhibit transcription. Specifically recognizes the sequence 5'-CCGGGTA-3' or 5'-CGGGTRR-3' (where R is any purine). A member of the general regulatory factors (GRFs) which act as genome partitioners. Acts as a chromatin insulator which are known as STARs (Subtelomeric anti-silencing region). STARs prevent negative or positive transcription influence by extending across chromatin to a promoter. Present with 7510 molecules/cell in log phase SD medium.
