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-α subtypes only differ in their sequences by one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end. IFNA2 (Interferon Alpha 2) is a Protein Coding gene. This gene is a member of the alpha interferon gene cluster on chromosome 9. The encoded protein is a cytokine produced in response to viral infection. Type I Interferons (IFNs) are well-known cytokines that exert antiviral activity, antitumor activity, and immunomodulatory effects.\u003c\/p\u003e\u003ch2\u003eBiological significance and function\u003c\/h2\u003e\u003cp\u003eFunctionally, \u003cstrong\u003eIFN-α\u003c\/strong\u003e mediates intercellular communication in immune and stress-response settings through receptor engagement and downstream transcriptional programs.
