Receptor binding properties of the influenza virus hemagglutinin as a determinant of host range.

abstract：:Picornavirus 5' NCRs contain IRES elements that have been divided into two groups, exemplified by PV (type 1) and EMCV (type 2). These elements are functionally related and have an intriguing level of structural and sequence similarity. Some conserved RNA sequences and/or structures may correspond to cis-acting elemen...
