SET1B complex associates with CXXC1 (also known as CFP1) and WDR82 proteins, which interact with the C-terminus and the N-terminus of SETD1B, respectively (Lee et al. 2007; Lee and Skalnik 2008; Wu et al. 2008; van Nuland et al. 2013). The association of CXXC1 and the WRAD complex with the C-terminus of SETD1B increases the protein stability of SETD1B (Lee et al. 2007). WDR82 binds to RNA polymerase II phosphorylated on serine S5 of heptad repeats during transcription initiation and may act to recruit the SET1B complex to promoters of transcriptionally active genes (Lee and Skalnik 2008). The association of WDR82 with chromatin likely requires prior ubiquitination of histone H2B (Wu et al. 2008). SETD1A may be the preferential interaction partner of WDR82 compared with SETD1B (Wu et al. 2008). Based on quantitative analysis in HeLa cells, CXXC1 may bind the SET1B complex as a dimer (van Nuland et al. 2013).
