RBBP4 is present in protein complexes that has been implicated in chromatin remodeling which is an integral component of transcriptional silencing.
It is present in protein complexes involved in histone acetylation and chromatin assembly. It is part of the Mi-2/NuRD complex that has been implicated in chromatin remodeling and transcriptional repression associated with histone deacetylation. This encoded protein is also part of corepressor complexes, which is an integral component of transcriptional silencing.
