Cloning, Exogenous Expression and Function Analysis of Interferon-γ from Gadus macrocephalus.

ABSTRACT: Interferon γ (IFN-γ) is now considered to be one of the key molecules in the regulation of innate and adaptive immunity. The function of IFN-γ is best described in humans, but less of IFN-γ in fish species has been described at protein level. In the present study, IFN-γ from Gadus macrocephalus (GmIFN-γ) has been examined in terms of bioinformatics, prokaryotic expression, yeast expression, antiviral activity and immune regulatory function. The cDNA of GmIFN-γ contains an open reading frame of 570 nucleotides, coding 189 amino acids. The mature protein contains a nuclear localization signal motif and an obvious IFN-γ signature sequence at the C-terminal. GmIFN-γ is very similar to that of Atlantic cod, with homology up to 89.89%, but less than 32% to other species. GmIFN-γ can be de
