Inhibitor of rna polymerase ii
Abstract
An inhibitor of RNA polymerase II is described, wherein said inhibitor is selected a moiety which targets a protein selected from cyclin kinase 12 (CDK12) or its recruiting protein PAF1C. Particular examples of such inhibitors are polypeptides expressed by a gene selected from lldD, lldR, nlpD or rfaH of a bacterial species, such as a commensal bacteria or asymptomatic carrier, or a variant of said protein. Inhibitors may be based upon bacterial Sigma S or NplD proteins. These inhibitors are useful in therapies, to suppress protein expression. Thus they may be used as immunosuppressants, anti-inflammatory or anti-infection agents.
Claims
exact text as granted — not AI-modified1 . A pharmaceutical composition comprising an inhibitor of RNA polymerase II and a pharmaceutically acceptable carrier, wherein said inhibitor targets a protein selected from cyclin kinase 12 (CDK12) or its recruiting protein PAF1C.
2 . The pharmaceutical composition according to claim 1 wherein the inhibitor is a polypeptide expressed by a gene selected from lldD, lldR, nlpD or rfaH of a bacterial species, or a variant of said protein.
3 . The pharmaceutical composition according to claim 2 wherein the bacteria is a commensal bacteria or an asymptomatic carrier.
4 . The pharmaceutical composition according to claim 3 wherein the bacteria is asymptomatic bacteriuria (ABU).
5 . The pharmaceutical composition according to claim 2 wherein the bacteria is an E. coli strain.
6 . The pharmaceutical composition according to claim 5 wherein the bacteria are E. coli 83972.
7 . The pharmaceutical composition according to claim 1 wherein the inhibitor is a Sigma S protein or a variant thereof or an active fragment of either of these.
8 . The pharmaceutical composition according to claim 7 wherein the Sigma S protein is e# SEQ ID NO 1 or SEQ ID NO 2 or SEQ ID NO 3.
9 . The pharmaceutical composition according to claim 1 wherein the inhibitor is a bacterial NplD protein, or a variant thereof, or an active fragment of either of these.
10 . The pharmaceutical composition according to claim 9 wherein the bacterial NplD protein is SEQ ID NO 4.
11 . The pharmaceutical composition according to claim 2 wherein the inhibitor is secreted by the bacteria.
12 . The pharmaceutical composition according to claim 9 wherein the inhibitor is of less than 3 kDa in molecular weight.
13 . The pharmaceutical composition according to claim 2 wherein the inhibitor is synthetic.
14 . (canceled)
15 . A method for preparing an inhibitor of RNA polymerase II that is expressed by a bacterial species which comprises culturing suitable bacteria in a culture medium, and isolating a factor having RNA polymerase II inhibitor activity from the supernatant.
16 . (canceled)
17 . A method for providing immunosuppression, anti-inflammatory or anti-infection therapy to a patient in need therefore, the method comprising administering to the patient an effective amount of an inhibitor of RNA polymerase II.
18 - 27 . (canceled)
28 . The method of claim 17 , wherein the inhibitor is a polypeptide expressed by a gene selected from lldD, lldR, nlpD or rfaH of a bacterial species, or a variant of said protein.
29 . The method of claim 17 , wherein the inhibitor is a bacterial NplD protein, or variant thereof, or active fragment of either of these.
30 . The method of claim 29 , wherein the bacterial NplD protein is SEQ ID NO 4.
31 . The method of claim 17 , wherein the inhibitor is a Sigma S protein, or a variant thereof, or an active fragment of either of these.
32 . The method of claim 31 , wherein the Sigma S protein is SEQ ID NO 1 or SEQ ID NO 2 or SEQ ID NO 3.Join the waitlist — get patent alerts
