| Outline of Final Research Achievements |
Signal transducing adaptor protein-2 (STAP-2) is an adaptor protein, which interacts with several signaling or transcriptional molecules. In this study, we found that STAP-2 enhances in vivo inflammatory (DSS-induced colitis) and immune responses (T-cell responses after the stimulation of T-cell receptor) as well as tumorigenesis of chronic myelogenous leukemia and melanoma. In BCR-ABL-mediated signals, STAP-2 expression changed the expression patterns of chemokine receptors, resulting in unique proliferation via interactions between CCR7 and its ligands (CCL19 or CCL21). Our results clearly indicate possible diseases for a novel STAP-2-targetting therapy.
