In mouse, the interferon-inducible Mx protein is
responsible for a specific antiviral state against influenza virus
infection. The protein encoded by this gene is similar to the mouse
protein as determined by its antigenic relatedness, induction
conditions, physicochemical properties, and amino acid analysis.
This cytoplasmic protein is a member of both the dynamin family and
the family of large GTPases. Two transcript variants encoding the
same protein have been found for this gene.
