Histone deacetylase and methods of use thereof
The present invention provides nucleic acid molecules that encode histone deacetylase, as well as recombinant vectors and host cells that include the subject nucleic acid molecules. Also provided are histone deacetylase polypeptide compositions. The histone deacteylase nucleic acid molecules are useful in a variety of diagnostic and therapeutic applications, which are also provided.
1. An in vitro method of identifying an agent that reduces enzymatic activity of histone deacetylase-7 (HDAC-7), the method comprising:
a) contacting an enzymatically active HDAC-7 polypeptide with a test agent, wherein said HDAC-7 polypeptide has at least 95% amino acid sequence identity to the amino acid sequence set forth in SEQ ID NO:02; and
b) determining the effect, if any, of the test agent on enzymatic activity of the HDAC-7 polypeptide.
2. The method according to claim 1 , wherein the HDAC-7 polypeptide is encoded by a nucleic acid present in a eukaryotic expression vector and is expressed in a eukaryotic cell.
3. An in vitro method of identifying an agent that reduces enzymatic activity of histone deacetylase-7 (HDAC-7), the method comprising:
a) contacting an enzymatically active HDAC-7 polypeptide with a test agent, wherein the HDAC-7 polypeptide lacks amino terminal amino acid residues 1-437 of SEQ ID NO:2, and comprises amino acids 438 to 912 of the amino acid sequence set forth in SEQ ID NO:2; and
b) determining the effect, if any, of the test agent on enzymatic activity of the HDAC-7 polypeptide.
4. The method of claim 1 , wherein the HDAC-7 polypeptide is at least 95% pure.
5. The method of claim 1 , wherein the HDAC-7 polypeptide comprises a polypeptide that provides a detectable signal.
6. The method of claim 1 , wherein the candidate agent is an organic compound.
7. The method of claim 1 , wherein the method is a cell-free method.
8. The method of claim 2 , wherein the eukaryotic cell is an immortalized cell line.
9. The method of claim 3 , wherein the HDAC-7 polypeptide is at least 95% pure.
10. The method of claim 3 , wherein the HDAC-7 polypeptide comprises a polypeptide that provides a detectable signal.
11. The method according to claim 3 , wherein the HDAC-7 polypeptide is encoded by a nucleic acid present in a eukaryotic expression vector and is expressed in a eukaryotic cell.
12. The method of claim 3 , wherein the candidate agent is an organic compound.
13. The method of claim 3 , wherein the method is a cell-free method.
14. The method of claim 11 , wherein the eukaryotic cell is an immortalized cell line.
