Human recombinant PB1-4 bromodomain (fourth 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 in PB1-4, occur frequently in renal cancers. PB1-4 shows binding affinity for two singly acetylated histone H3 peptides (H3K37Ac and H3K122Ac).

TAG(S): C-terminal His and Strep-tags
MW: 19.4 kDa
EXPRESSION SYSTEM: E. coli
SUPPLIED AS: Solution of purified recombinant protein in 50 mM Tris/HCl, pH 7.5, 500 mM NaCl, 1 mM TCEP, 10% glycerol (v/v)
STORAGE: -70°C. Thaw quickly and store on ice before use. The remaining, unused, undiluted protein should be snap frozen, for example in a dry/ice ethanol bath or liquid nitrogen.
