- ITAM ITAM
- a gene encoding a novel membrane protein derived from a mast cell and considered to be involved in the control of a signal transduction pathway of the mast cell is provided. Expression properties of these gene products and their binding to proteins involved in signal transduction Therefore, these are considered to suppress or activate signal transduction after mast cell antigen stimulation according to the following working hypothesis.
- MC-PIR2 associates with the signaling molecules DAP10, DAP12 and FcRr having ITAM
- MC-PIR2 causes activation through a phosphorylating enzyme such as Src family kinase or PI3 kinase (Wu, J. et al. (1999), Science 285, 730-732, Lanier, LL et al. (1998), Nature 391, 703-707, Vivier, E. et al. (1992), Int. Immunol. 4, 1313- 1323). Therefore, for example, inhibiting the association between MC-PIR2 and a signaling molecule having these ITAMs is expected to be able to suppress activation signaling. That is, MC-PIR2 itself may be a target molecule of a mast cell activation signal transduction inhibitor.
- the gene expression products of MC-PIRK MC-PIR2, and their human homologs can be used for screening natural ligands, compounds that mimic their effects, or antibodies.
- Ligands, compounds or antibodies obtained by screening using these expression products may inhibit mast cell activation signal transduction and become an anti-allergic agent with a novel mechanism of action.
