Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). [1] Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is located upstream of the interferon genes. [2]
IRF3 is a member of the interferon regulatory transcription factor (IRF) family. [5] IRF3 was originally discovered as a homolog of IRF1 and IRF2.IRF3 has been further characterized and shown to contain several functional domains including a nuclear export signal, a DNA-binding domain, a C-terminal IRF association domain and several regulatory phosphorylation sites.

Closed-loop regulator circuits using the TL431 are always designed to operate in high transconductance mode, with I CA no less than 1 mA (point D on the current-voltage curve). [ 8 ] [ 7 ] [ 2 ] For better control loop stability, optimal I CA should be set at around 5 mA, although this may compromise overall efficiency.
