D [auth A] | PF02765 | Telomeric single stranded DNA binding POT1/CDC13 (POT1) | Telomeric single stranded DNA binding POT1/CDC13 | 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 ... | Domain |
E [auth B] | PF07404 | Telomere-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 ... | Domain |
