Technical Data
IRF1 (Interferon Regulatory Factor 1, IRF-1, MAR)
IRF1 (interferon regulatory factor 1) is a 45kD member of the IRF family of proteins. It is induced by TLR9 and INF-g stimulation, and positively regulates the expression of IFN-b, iNOS and 1L-12 p35. Human IRF1 is 325aa in length. It contains an N-terminal DNA-binding basic region aa1-140 and an acidic C-terminus aa141-325. Lys275 and 299 can be SUMOylated, which blocks activity, or ubiquinated at Lys299, which initiates degradation. There is a splice variant that shows an 11aa substitution for the C-terminal 86aa. Over aa171-325, human IRF1 shares 83aa identity with both canine and porcine IRF1.

Suitable for use in Western Blot. Other applications not tested.
