General description
Interferon beta (UniProt: P01574; also known as IFN-beta, Fibroblast interferon) is encoded by the IFNB1 (also known as IFB, IFNB) gene (Gene ID: 3456) in human. Interferons are divided into three families (type I, II, and III) based on their sequence homology. Type I is the largest group that includes Interferons alpha and beta. Interferons are the primary defensive cytokines against pathogens and display strong antiviral activities. They also display anti-bacterial and anti-cancer properties. Interferon beta is a fibroblast generated monomeric cytokine that is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off to generate the mature form. Signaling by interferon beta involves its binding to IFNARR1-IFNAR2 heterodimeric receptor, which regulates the expression of several genes by JAK/STAT pathway. However, it can also function by binding to INFAR1 alone and independently of JAK/STAT pathway. In immune cells it reduces antigen presentation and T cell proliferation and alters matrix metalloproteinase expression. Interferon beta is reported to reduce the levels of proinflammatory cytokines and increase the levels of anti-inflammatory cytokines. Interferon beta displays about 30% amino acid sequence homology with interferon alpha (produced by leukocytes), however, they both share the same receptor and have very similar biological activities. They both confer resistance to viral infections on target cells, inhibit cell proliferation and regulate expression of MHC class I. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
