Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 42 kDa.


  • FunctionComponent of the CST complex, a complex that binds to single-stranded DNA and is required to protect telomeres from DNA degradation. The CST complex binds single-stranded DNA with high affinity in a sequence-independent manner, while isolated subunits bind DNA with low affinity by themselves. In addition to telomere protection, the CST complex has probably a more general role in DNA metabolism at non-telomeric sites.
  • Sequence similaritiesBelongs to the STN1 family.
    Contains 1 OB DNA-binding domain.
  • Cellular localizationNucleus. Chromosome > telomere.
