Protein
Telomere-binding protein subunit alpha
Function
May function as protective capping of the single-stranded telomeric overhang. May also participate in telomere length regulation during DNA replication. Binds specifically to the T4G4-containing extension on the 3'strand and protects this region of the telomere from nuclease digestion and chemical modification.
Similarity
Belongs to the telombin family.
