Cell death-related nucleases and their uses
View Patent ↗An assay uses apoptotic nucleases to screen for apoptosis modulators, in a method of modulating apoptosis, and in a method of aiding in a diagnosis of a disease, among other methods. materials for use in the assay include isolated or recombinant polypeptides and polynucleotides, compositions comprising those isolated or recombinant polypeptides and polynucleotides, vectors, transgenic organisms, and integrated systems among other aspects.
1. A method of screening for an apoptosis modulator by using cell death-related nucleases (CRN), the method comprising:
(a) contacting at least one candidate apoptosis modulator with a CRN material comprising a polypeptide having nuclease activity and at least 98% sequence identity with respect to SEQ ID NO:2 or a fragment thereof; and
(b) detecting a modulated activity and/or level of said polypeptide, thereby identifying the apoptosis modulator.
2. The method of claim 1 , wherein the step of detecting comprises detecting DNA degradation.
3. The method of claim 1 , wherein the CRN material comprises the polypeptides of SEQ ID NO. 2.
4. The method of claim 1 , further comprising steps of
isolating the apoptosis modulator; and
converting the apoptosis modulator into a dosage form in an effective amount for modulating apoptosis in an organism.
