Abstract
This invention discloses endogenous calcineurin inhibitors, Calcipressin, Csp1, Csp2, and Csp3, as shown in SEQ ID Nos: 4-5, or 24. This invention also discloses nucleic acid sequences that can activate or regulate transcription of the CSP family of polypeptides.
Claims13
A method for identifying a compound that modulates the activity or level of a calcipressin (Csp) protein, comprising contacting a cell comprising a Csp protein with a test compound and determining the level or activity of the Csp protein in the cell, wherein a higher or lower level or activity of the Csp protein in the cell contacted with the test compound relative to a cell that was not contacted with the test compound indicates that the test compound is a compound that modulates the activity or level of the Csp protein, wherein said activity of the Csp protein is the binding activity of the Csp protein to calcineurin or the inhibitory activity of the Csp protein toward calcineurin, and wherein the Csp protein comprises an amino acid sequence that has at least 95% or about 95% sequence identity to amino acids 50-197 of SEQ ID NO:
- 4.
A method for identifying a compound that modulates the activity or level of a calcipressin (Csp) protein, comprising contacting a cell comprising a Csp protein with a test compound and determining the level or activity of the Csp protein in the cell, wherein a higher or lower level or activity of the Csp protein in the cell contacted with the test compound relative to a cell that was not contacted with the test compound indicates that the test compound is a compound that modulates the activity or level of the Csp protein, wherein said activity of the Csp protein is the binding activity of the Csp protein to calcineurin or the inhibitory activity of the Csp protein toward calcineurin, and wherein the Csp protein comprises an amino acid sequence that has at least 95% or about 95% sequence identity to SEQ ID NO:
- 4.
