Fig 1. Atypical PKCζ exists in a complex with HDAC6. HA-PKCζ and FLAG-HDAC6 were transfected into HEK cells and reciprocal immunoprecipitations performed using antibodies for each tag as described in Materials and Methods
Fig 2. Atypical PKCζ phosphorylates HDAC6. (A) GST-deletion constructs of HDAC6 were expressed in HEK cells and captured by GST-pulldown assay.
Fig 3. Phosphorylation by atypical PKCζ upregulates the deacetylase activity of HDAC6
Fig 4. Atypical PKCζ regulates HDAC6 deacetylase activity. Parental MEF cells were transfected to overexpress either HA-HDAC6 or myc-PKCζ or were treated with HDAC6 inhibitor tubacin (10μM for 4 hours) or aPKC inhibitor (myristoylated pseudosubstrate—20μM
