The present invention relates to regulation of IgE-receptor-mediated mast cell degranulation. More particularly, the present invention is directed to nucleic acids encoding CD43 (also called leukosialin or leukocyte large sialoglycoprotein), which is involved in modulation of IgE-receptor-mediated mast cell degranulation. The invention further relates to methods for identifying and using agents, including small molecule chemical compositions, antibodies, siRNA, antisense nucleic acids, and ribozymes, that modulate IgE-receptor-mediated mast cell degranulation via modulation of CD43 and CD43-related signal transduction; as well as to the use of expression profiles and compositions in diagnosis and therapy related to diseases such as allergies and asthma. |
