DESCRIPTION:Human recombinant PB1-3 bromodomain (third bromodomain of polybromo-1). PB1, a chromatin targeting component of the PBAF (SWI/SNF-B) chromatin-remodeling complex, comprises six tandem bromodomains. Mutations in PB1, including PB1-3, occur frequently in renal cancers. PB1-3 shows binding affinity for various acetyllysines in singly acetylated histone peptides (e.g. H2AK15Ac).
