D [auth A]PF22236Telomere end-binding protein alpha subunit OB2 domain (TEBP_OB2-like)Telomere end-binding protein alpha subunit OB2 domainThis entry represents the second OB-fold domain (OB2) of the telomere end-binding protein (TEBP) alpha subunit. Similar to the first OB-fold domain (OB1), this domain binds to ssDNA [1-3].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 protects telomere-ends from attack by DNA-repair mechanisms [5,6].

E [auth B]PF07404Telomere-binding protein beta subunit (TEBP beta) (TEBP_beta)Telomere-binding protein beta subunit (TEBP beta)This domain represents the OB fold from several telomere-binding protein beta subunits which appear to be specific to the family Oxytrichidae. Telomeres are specialised protein-DNA complexes that compose the ends of eukaryotic chromosomes. Telomeres ...This domain represents the OB fold from several telomere-binding protein beta subunits which appear to be specific to the family Oxytrichidae. Telomeres are specialised protein-DNA complexes that compose the ends of eukaryotic chromosomes. Telomeres protect chromosome termini from degradation and recombination and act together with telomerase to ensure complete genome replication. TEBP beta forms a complex with TEBP alpha and this complex is able to recognise and bind ssDNA to form a sequence-specific, telomeric nucleoprotein complex that caps the very 3' ends of chromosomes [1, 2].
