POT1PC is able to accommodate heterogeneous ssDNA ligands. Pot1 proteins are the proteins responsible for binding to and protecting the 3' single-stranded DNA (ssDNA) overhang at most eukaryotic telomeres [1].

It includes the proteins POT1 and CDC13 which have been shown to regulate telomere length, replication and capping [2-4]. POT1 is one component of the shelterin complex that protects telomere-ends from attack by DNA-repair mechanisms [5,6].
