Telomeric repeat-binding factor 2-interacting protein 1 also known as repressor activator protein 1 (Rap1) is a protein that in humans is encoded by the TERF2IP gene. [5] [6]
TERF2IP has been shown to interact with Ku80, [7] Rad50 [7] and TERF2. [5] [7] [8] Upon interaction, TERF2IP/TERF2 complex has been shown to bind to telomeric junction sites with higher affinity [9]
