Biological Activity
Description
IFN-alpha 1 (IFNA1), belongs to type I interferon family, is produced by macrophages with antiviral activities[1]. IFN-alpha 1 involves in the activation of JAK1 and TYK2 pathway[4], exerts function by inhibiting viral replication as well as modulating immune response[3]. IFN-alpha 1/IFNA1 Protein, Mouse (P.pastoris, His) is produced in P.pastoris yeast cells with a C-Terminal His-tag.
Background
IFN-alpha 1 (IFNA1; IFN-α1), belongs to the alpha/beta interferon family, is produced by macrophages with antiviral activities[1]. Interferon (IFN) is originally identified as a substance ‘interfering’ with viral replication in vitro. IFN-α/β and related molecules are classified as type I IFNs, as for the other two types of type II IFN (IFN-γ) and type III IFNs (IFN-λ), respectively[2].
IFNs binds to one of three type-specific receptors, which leads to the activation of JAK1 and TYK2[3]. This signal transduction results in phosphorylation of STAT1 and STAT2 and eventually in an association with IFN regulatory factor 9 (IRF9) and formation of the IFN-stimulated gene factor 3 (ISGF3) complex. Thus the ISGF3 complex induces transcription of IFN-stimulated genes (ISGs), with subsequent immunomodulatory effects on both innate and adaptive immune responses[4].
The interactions of type I IFN with the immune system is important for the generation of a durable antitumor response through its effects on dendritic cells (DC)[5]. IFN has been widely used for animal disease model, and the sequence of amino acids in IFNA1 protein of mouse is very different from human (62.96%).
Verified Bioactivity
Measured in antiviral assays using L929 cells infected with vesicular stomatitisvirus (VSV) and the ED50 is 20-100 pg/mL.
