Abstract

The growing number of proteins controlled by reversible acetylation suggests the existence of a large number of acetyltransferases and deacetylases. Here, we report the identification of a novel class II histone deacetylase, HDAC10. Homology comparison indicates that HDAC10 is most similar to HDAC6. Both contain a unique, putative second catalytic domain not found in other HDACs. In HDAC10, however, this domain is not functional. This tandem organization of two catalytic domains confers resistance to the inhibitors trapoxin B and sodium butyrate, which potently inhibit the deacetylase activity of all other HDAC members. Thus, HDAC10 and HDAC6 share unusual structural and pharmacological characteristics. However, unlike HDAC6, which is normally a cytoplasmic deacetylase, HDAC10 resides in both the nucleus and cytoplasm. In the nucleus, when tethered to a promoter, HDAC10 represses transcription independent of its deacetylase activity, indicating that HDAC10 contains a distinct transcriptional repressor domain. These observations suggest that HDAC10 might uniquely play roles both in the nucleus, as a transcriptional modulator, and in the cytoplasm in an unidentified role. Together, our results identify HDAC10 as a novel deacetylase with distinct structure, pharmacology and localization and further expand the complexity of the HDAC family.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
