with HDAC4 or HDAC4-K559R followed by immunoprecipitation using the anti-HDAC4
antibodies and an assay for histone deacetylase activity (Figure 4B). Although
the two proteins were expressed at a similar level (inset), the HDAC activity
associated with HDAC4-K559R was significantly reduced, to a level barely above that
of endogenous HDAC4 (compare lane 3 with lanes 1 and 2).""" ;
