Molecular Cloning, Characterization, and Expression of Two Myeloid Differentiation Factor 88 (Myd88) in Pacific Oyster, Crassostrea gigas
Abstract Myeloid differentiation factor 88 ( MyD88 ) is a universal adaptor protein and plays an important role in the signal transduction of Toll/interleukin‐1 receptor ( TIR / IL‐1R ) family. In this study, two novel molluskan MyD88 family members (named as CgMyD88 ‐1 and CgMyD88 ‐2) were identifi...
