molecular function
    GO:0043047    single-stranded telomeric DNA binding    Interacting selectively and non-covalently with single-stranded telomere-associated DNA.
biological process
    GO:0016233    telomere capping    A process in which telomeres are protected from degradation and fusion, thereby ensuring chromosome stability by protecting the ends from both degradation and from being recognized as damaged DNA. May be mediated by specific single- or double-stranded telomeric DNA binding proteins.
cellular component
    GO:1990879    CST complex    A complex formed by the association of Cdc13 (CTC1 in mammals) with Stn1 in yeast (OBFC1 in mammals) and Ten1 protein (also TEN1 in mammals) with single-stranded telomeric DNA. The CST complex plays a role in telomere protection.
