PCAF domain analysis and the relationship with p300. (A) Heterodimer–RARE complexes (∼2 pmoles) were incubated with 2 pmoles of recombinant N-p300 (amino acids 1–670) alone (lanes 1,2) or along with 1 (+) and 2 (++) pmoles of PCAF (lane 3–6) in the presence (+) or absence (−) of 1 μm 9-cis RA. (B) PCAF domain analysis: 2 pmoles of rPCAF lacking the carboxy-terminal domain (ΔC) or amino-terminal domain (ΔN1 and ΔN2, top) were incubated with heterodimer–RARE complexes (1 μg of heterodimer) in the presence (+) or absence (−) of 1 μm 9-cis RA. Binding was detected with anti-PCAF antibody.
