This domain is found in Cdc13 proteins in several Candida species. The Cdc13-Stn1-Ten1 complex is crucial for telomere protection. This domain is the C-terminal OB4 domain and is responsible for dimerization. Dimerization of Cdc13 is important for high-affinity DNA binding [1].	Domain

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 p ...	This domain binds single stranded telomeric DNA and adopts an OB fold [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].	Domain
