The protein family, Interleukin-28A, plays an important role in modulating the immune system. This protein family is induced by viral infection and interacts with a class II receptor [1]. This family of proteins is found in eukaryotes. Proteins in this family are typically between 145 and 195 amino acids in length.	Domain
