Methods of modulating and of identifying agents that modulate intracellular calcium
First Claim
Patent Images
1. A method of identifying an agent that modulates intracellular calcium, comprising:
- contacting one or more test cells or a portion thereof comprising one or more proteins that is (are) at least about 35% homologous to the protein encoded by Drosophila gene CG4536 or CG5842 over at least about 40% of the encoded protein and that provides for store-operated calcium entry with a test agent, wherein the portion of the cell comprises the one or more proteins;
monitoring the effect(s) of the test compound on store-operated calcium entry; and
identifying a test agent as an agent if it has an effect on store-operated calcium entry.

18. A method of identifying an agent that modulates intracellular calcium, comprising:
-
monitoring the effects of an agent on store-operated calcium entry, wherein the agent modulates the activity of, the interaction of, the level of or binds to a protein that provides for store-operated calcium entry and that is at least about 35% homologous to the protein encoded by Drosophila gene CG4536 or CG5842 over at least about 40% of the encoded protein; and
identifying a test agent as an agent that modulates intracellular calcium if it has an effect on store-operated calcium entry. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 29, 32, 33, 34)

- 42. A method of modulating store-operated calcium entry, comprising modulating the level of, expression of, activity of or molecular interactions of a protein in a cell that has altered store-operated calcium entry, wherein the protein is at least about 35% homologous to the protein encoded by Drosophila gene CG4536 or CG5842 over at least about 40% of the encoded protein and that provides for store-operated calcium entry, and whereby store-operated calcium transport into the cell is modulated.
- 45. A method of identifying a molecule that provides for store-operated calcium entry, comprising identifying a molecule that interacts with a protein that is least about 35% homologous to the protein encoded by Drosophila gene CG4536 or CG5842 over at least about 40% of the encoded protein and that provides for store-operated calcium entry, thereby identifying molecules involved in modulating store-operated calcium entry.
