Targeting of long chain triacylglycerol hydrolase gene for tuberculosis treatment
View Patent ↗Disclosed herein are novel methods for screening for compounds useful in treating or preventing tuberculosis. In exemplary embodiments, screening methods are based on the implementation or manipulation of triacylglycerol hydrolase like polypeptides or polynucleotides encoding the same. The methods are useful in identifying agents active against TB infection.
1. A polynucleotide comprising a nucleic acid sequence encoding SEQ ID NO. 2, or a polypeptide having at least 90 percent identity to SEQ ID NO. 2, wherein said polynucleotide is in an expression vector.
2. The polynucleotide sequence of claim 1 , wherein said nucleic acid sequence comprises a sequence that encodes GDSAG (SEQ ID NO. 61).
3. The polynucleotide sequence of claim 1 , wherein said nucleic acid sequence comprises a sequence that encodes HGGG (SEQ ID NO. 68).
4. The polynucleotide sequence of claim 1 , wherein said nucleic acid sequence comprises a sequence that encodes GDSAG (SEQ ID NO. 61) and a sequence that encodes HGGG (SEQ ID NO. 68).
5. An agent which regulates the activity of a M. tuberculosis TG hydrolase (MTTGH) polypeptide, wherein said agent is an RNA molecule, an antisense oligonucleotide, or a ribozyme that targets a nucleic acid sequence that encodes SEQ ID NO. 2.
6. An isolated polypeptide d-comprising SEQ ID NO. 2.
7. A recombinant cell host containing a purified MTTGH polynucleotide or a recombinant vector comprising a MTTGH polynucleotide, wherein said MTTGH polynucleotide comprises a nucleic acid sequence that encodes SEQ ID NO. 2, or a polypeptide having at least 90 percent identity therewith.
