This family of proteins bind to DNA and to TBP (TATA box binding protein), TATA-binding protein (TBP)-related protein 2 (TRF2) and several polycomb factors. It is likely to function as a transcription regulator [1-2].

1: TIPT, a male germ cell-specific partner of TRF2, is chromatin-associated and interacts with HP1. Brancorsini S, Davidson I, Sassone-Corsi P; Cell Cycle. 2008;7:1415-1422. PMID:18418073

2: TIPT2 and geminin interact with basal transcription factors to synergize in transcriptional regulation. Pitulescu ME, Teichmann M, Luo L, Kessel M; BMC Biochem. 2009;10:16. PMID:19515240
