Methods and compositions targeting viral and cellular ITAM motifs, and use of same in identifying compounds with therapeutic activity

摘要

This invention provides methods of treating, reducing the incidence of, and inhibiting metastasis formation of carcinomas, sarcomas, Epstein-Barr virus-induced malignancies, B cell proliferative disorders, and mast cell activation disorders, comprising administering to a subject a compound that inhibits an interaction of a first protein and an immunoreceptor tyrosine-based activation motif (ITAM) of a second protein, and screening methods for identifying ITAM-inhibitory compounds and peptides. This invention also provides peptides that inhibit signaling by ITAMs.
