| Scientific Background: | RbAp46 (Retinoblastoma protein associated protein 46) and RbAp48 (Retinoblastoma protein associated protein 48) are highly homologous histone chaperones that play key roles in protein complexes that function to establish and maintain chromatin structure. RbAp46/48 are found in a number of protein complexes involved in chromatin remodeling (Mi-2β, NURF & NURD), transcriptional repression (Prc2, Sin3) and chromatin assembly (CAF1). Both RbAp46 and RbAp48 are specifically found in the catalytic cores of histone deacetylase (HDAC) complexes that promote transcriptional repression of target genes, including those repressed by the retinoblastoma tumor suppressor protein.RbAp46 binds to and enhances the activity of the type B histone acetyltransferase HAT1, an enzyme that acetylates histone H4 specifically at its Lys5 and Lys12 residues prior to their incorporation into nucleosomes during replication.RbAp48 is an evolutionarily conserved subunit of the chromatin assembly factor-1 (CAF-1) complex, where it associates with two other subunits, known as p150 and p60 in human cells. It is also reported that E2F-1 and RbAp48 are physically associated in the presence of RB1 and histone deacetylase, suggesting that RbAp48 could be involved in transcriptional repression of E2F-responsive genes. |
