Identification of a second group of type I IFNs in fish sheds light on IFN evolution in vertebrates.

In this report, three type I IFN genes were identified in rainbow trout (rt) Oncorhynchus mykiss and are classified into two groups based on their primary protein sequences: group I containing two cysteine residues; and group II containing four cysteines residues. The group I rtIFNs were induced in ... View More
