Structure of a bifunctional membrane-RNA binding protein, influenza virus matrix protein M1.
B.Sha, M.Luo.
 
  ABSTRACT  
 
Matrix protein (M1) of influenza virus is a bifunctional protein that mediates the encapsidation of RNA-nucleoprotein cores into the membrane envelope. It is therefore required that M1 binds both membrane and RNA simultaneously. The X-ray crystal structure of the N-terminal portion of type A influenza virus M1-amino acid residues 2-158-has been determined at 2.08 A resolution at pH 4.0. The protein forms a dimer. A highly positively charged region on the dimer surface is suitably positioned to bind RNA while the hydrophobic surface opposite the RNA binding region may be involved in interactions with the membrane. The membrane-binding hydrophobic surface could be buried or exposed after a conformational change.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
