TERF1-interacting nuclear factor 2 N-terminal(IPR029400)denotes the N-terminal domain of TERF1-interacting nuclear factor 2 (TINF2). It is a component of the shelterin complex (telomere), which is responsible for preserving and maintaining telomeres. TINF2 influences the assembly of the shelterin complex. One of its isoforms may also play a role in tethering telomeres to the nuclear matrix in humans.
