Application

Tubastatin A hydrochloride may be used in HDAC6-mediated cell signaling studies.

Biochem/physiol Actions

Tubastatin A increases the total numbers of mitochondria and restores the number of moving mitochondria in DRG neurons. It reverses the axonal loss in peripheral neurons in mouse model of Charcot-Marie-Tooth disease. Tubastatin A inhibits the deacetylation of α-tubulin in murine myoblasts.
Tubastatin A is a very selective HDAC6 inhibitor with an IC50 of 4 nM and 100 to over 1000-fold selectivity for HDAC6 over other HDAC classes.

Charcot-Marie-Tooth disease (CMT) is the most common inherited disorder of the peripheral nervous system. Mutations in the 27-kDa small heat-shock protein gene (HSPB1) cause axonal CMT or distal hereditary motor neuropathy (distal HMN). We developed and characterized transgenic mice expressing

Epigenetic mechanisms (i.e., histone post-translational modification and DNA methylation) play a role in regulation of gene expression. The pedunculopontine nucleus (PPN), part of the reticular activating system, manifests intrinsic gamma oscillations generated by voltage-dependent, high threshold N- and P/Q-type Ca2+

Microtubules are polymerized dimers of α- and β-tubulin that underlie a broad range of cellular activities. Acetylation of α-tubulin by the acetyltransferase ATAT1 modulates microtubule dynamics and functions in neurons. However, it remains unclear how this enzyme acetylates microtubules over
