Entrez Gene Summary for IFNA2 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. Use of the recombinant form of this protein has been shown to be effective in reducing the symptoms and duration of the common cold. [provided by RefSeq, Jun 2011]

GeneCards Summary for IFNA2 Gene

IFNA2 (Interferon, Alpha 2) is a Protein Coding gene. Diseases associated with IFNA2 include blue rubber bleb nevus syndrome and periarteritis nodosa. Among its related pathways are PI3K-Akt signaling pathway and TGF-Beta Pathway. GO annotations related to this gene include cytokine activity and type I interferon receptor binding. An important paralog of this gene is IFNE.
