Webb1 jan. 2002 · The first Toll protein was identified in Drosophila, where Toll functions to transmit extracellular signals into the cytoplasm to control dorsal–ventral patterning in the early embryo. Toll and many components in this signaling pathway also mediate antifungal response at post-embryonic stages. WebbWe have investigated the possible involvement of the p38 MAP kinase pathway in the Drosophilaimmune response. Two genes that are highly homologous to the mammalian p38 MAP kinase were molecularly cloned and characterized. Furthermore, genes that encode two novelDrosophilaMAP kinase kinases, D-MKK3 and D-MKK4, were identified.
