A FRAP of NOP53-mEGFP puncta in the nucleoplasm of HEK293T cells. B The NoLS of NOP53 was analyzed with NOD (www.compbio.dundee.ac.uk/software.html#3Dstructure) and verified in HEK293T cells. C Schematic of R motifs or M-R motifs distribution in NOP53 sequence and truncation of NOP53-IDR1/IDR2 sequence. R motifs were defined as the sequence pattern, RXn1R (n1 ≤ 2), while M-R motifs were defined as the sequence pattern, RXn1RXn2RXn3R (n1 ≤ 2, n3 ≤ 2, and n2 ≤ 20). D Distribution of NOP53-Rm-mEGFP, NOP53-Rm+NoLS-mEGFP and NOP53-Rm-del(41-159)-mEGFP in HEK293T cells. E The purified NOP53-Rm-mEGFP and NOP53-Rm+NoLS-mEGFP protein, but not NOP53-Rm-del(41-159)-mEGFP protein, formed droplets in vitro. One micromolar protein was used.
