Abstract
Myeloid differentiation factor 88 (MyD88) is an adaptor protein of Toll-like receptor (TLR) signalling pathways that activates the innate immune system. Herein, MyD88 was identified in the economically important freshwater fish Pelteobagrus fulvidraco. The complete 2156 bp PfMyD88 cDNA includes a 147 bp 5'-untranslated region (UTR), a 1133 bp 3'-UTR, and an open reading frame (ORF) of 876 bp encoding a 291 residue protein containing Death and Toll/interleukin-1 receptor (TIR) domains. The deduced protein sequence shares 88.8%, 73.8% and 59.3% identity with orthologs in Ictalurus punctatus, Danio rerio and Homo sapiens, respectively. qRT-PCR revealed expression in all tested tissues, highest in trunk kidney, followed by spleen, and lowest in muscle. After challenge with lipopolysaccharide (LPS) or polyriboinosinic polyribocytidylic acid (Poly I:C), PfMyD88 expression was up-regulated in blood, liver, head kidney and spleen. Thus, PfMyD88 acts in innate immunity in P. fulvidraco.
