概述

IFN-αs are proteins secreted by leukocyte.They are mainly involved in innate immune response against viral infection.The IFN-α family has 13 subtypes and 23 different variants.The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids.All IFN-α subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable.Many IFN-alpha subtypes differ in their sequences at only one or two positions.Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.
