Identification of Functional Domain(s) of Fibrillarin Interacted with p2 of Rice stripe virus

Figure 1

Three functional domains of NbFib2. NbFib2-1: N-terminal fragment from 1 aa to 130 aa, containing a GAR region and a glycine- and arginine-rich domain. RBS means RNA binding sites. NbFib2-2: the central RNA-binding domain from 131 aa to 221 aa. NbFib2-3: the C-terminal fragment from 222 aa to 314 aa, containing an α-helical domain.
