Expression and cilia associated localization of Histone deacetylases 6 in Xenopus.

Histone deacetylases (HDACs) are key posttranslational modulators of the proteome. We show that expression of histone deacetylase 6 ( hdac6 ) is dynamic and appears in a tissue specific manner throughout embryonic development of the frog Xenopus laevis . Interestingly, hdac6 transcripts often associate with ciliated tissues, like the left-right organizer at neurula stage or the pronephros. In the embryonic skin, Hdac6 protein localizes to the cilia base, suggesting a functional link.
