Known human interacting protein partners of BORIS (yellow) and CTCF (blue). Squares indicate the proteins observed to interact with both BORIS and CTCF. van de Nobelen et al., 2010 identified UBF as a common interacting partner for both BORIS and CTCF [16]. All other proteins shown to associate with BORIS were identified by Nguyen et al., 2008 and isolated using yeast 2-hybrid screening techniques with N-terminus segments of the BORIS protein as bait [25]. Proteins shown to interact with CTCF were all discussed in an excellent review published by Ohlsson et al., 2010 [27].
