Ta. Timofeeva et al., Identification of the protease-binding domain in the N-terminal region of influenza virus A matrix protein M1, MOL BIOL, 35(3), 2001, pp. 411-416
A region responsible for protease binding by influenza virus A matrix prote
in M1 was identified. Trypsin binding was observed with the N-proximal 9-kD
a fragment obtained by cleaving M I with formic acid. The binding was inhib
ited by monoclonal antibodies (mAb) to region 46-70 of M1 and by an antiser
um to region 21-45, whole as mAb to the middle and C-terminal regions had n
o effect. Thus, the protease-binding domain was mapped to the N-terminal pa
rt of M1.
