Interferon, alpha 5 (IFNA5) belongs to the alpha/beta interferon family. IFNA5 is the only IFNA subtype detected in normal liver, while a mixture of subtypes is observed in the liver tissue of patients with chronic hepatitis C. Interferons are produced by macrophages, IFN-alpha has antiviral activities. Interferon stimulates the production of two enzymes: a protein kinase and an oligoadenylate synthetase. IFN-alpha, the first cytokine to be produced by recombinant DNA technology, has emerged as an important regulator of growth and differentiation, affecting cellular communication and signal transduction pathways as well as immunological control. Originally discovered as an antiviral substance, the efficacy of IFN-alpha in malignant, viral, immunological, angiogenic, inflammatory, and fibrotic diseases suggests a spectrum of interrelated pathophysiologies. IFN-alpha emerged as a prototypic tumor suppressor protein that represses the clinical tumorigenic phenotype in some malignancies capable of differentiation.
生物活性
Recombinant human IFN-α bioactivity is measured by inhibition of the proliferation of HT-29 cells.The EC50 for this effect is typically 0.07 ng/mL.
48.1 kDa, under reducing conditions; 45. 0 & 79.0 kDa, under non-reducing conditions.

Recombinant Human IFN-alpha G/IFNA5 Protein (rp222555) - SDS-PAGE
3 μg/lane of Recombinant Human IFN-alpha G/IFNA5 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 48.1 kDa under reducing conditions and 79.0 kDa under non-reducing conditions.
There are multiple pairs of disulfide bonds in the protein sequence. Disulfide bonds cause the protein to present as a polymer in a non-reducing conditions (Uniprot ID: P01569).
