The data indicate a fundamental role for the GAV N protein proline/arginine-rich domain in nucleating genomic ssRNA to form nucleocapsids. In a preliminary attempt to identify an RNA packaging signal in the GAV genome, EMSAs were performed using ssRNAs synthesized to various genome regions including (i) an ORF1b gene 39-region spanning the relative position to the genome packaging signal identified in MHV [28] , (ii) a 39-terminal genome region corresponding in position to the region in the infectious bronchitis virus (IBV) genome reported to contain an RNA binding domain [29] and (iii) the 59-genomic RNA terminus which, in coronaviruses, has also been reported to interact specifically with N protein [30] . ./cache/cord-281124-4nhy35xn.txt ./txt/cord-281124-4nhy35xn.txt
