CDKN1C and neuroblastoma: Topark-Ngarm et al. (2006) showed that CTIP2 complexes from human neuroblastoma cells contained GATAD2A/B, MTA1/2, RBBP4/7, or HDAC1/2. These NuRD subunits were recruited in a CTIP2-dependent manner to a plasmid harboring the promoter region of p57KIP2, encoding a cyclin-dependent kinase inhibitor, and conferred repression (Figure 7C).
