The RUNX1:CBFB complex can bind to transcriptional co-repressors SIN3A and SIN3B. The interaction with SIN3A has been studied in more detail. Binding to SIN3A leads to transcriptional repression of RUNX1 target genes, which may involve SIN3A-mediated recruitment of histone deacetylases (HDACs) to target promoters (Lutterbach et al. 2000). Arginine methylation of RUNX1 by PRMT1 inhibits association of RUNX1 with SIN3A (Zhao et al. 2008). RUNX1 transcriptional repressor complex with SIN3A also includes histone arginine methyltransferase PRMT6 and HDAC1 (Herglotz et al. 2013).
