Functional characterization of heptad repeat 1 and 2 mutants of the spike protein of severe acute respiratory syndrome coronavirus.

abstract：:A new group of nucleocytoplasmic shuttling proteins has recently been identified in the structural proteins encoded by several alphaherpesvirus UL47 genes. Nuclear import and export signals for the bovine herpesvirus type 1 UL47 protein (VP8 or bUL47) have been described previously. Here, we study the trafficking of b...
