Binds the telomeric double-stranded TTAGGG repeat and negatively regulates telomere length. Involved in the regulation of gene expression. 52 binding sites have been identified, distributed over 15 chromosomes. 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. Homodimer. Localizes to synapsed chromosomes during meiosis. Present with 6380 molecules/cell in log phase SD medium.
