Figure Lengend Snippet: Photoactivation of FUS condensation. (A) Scheme of full-length FUS protein (top) and chimeric constructs used in this study (bottom) (IDR, intrinsically disordered region; RRM and RGG, RNA-binding motives; Zn, Zn-finger). (B) Cartoon of the imaging assay in HEK cells. (C) Representative images (z-projections) before (left) and after (right) photoactivation of 1 min at 0.02 mW 488 nm-laser power at the output. Scale bar, 10 μm. (D) Line profiles of highlighted regions in (C) (dotted line, before activation; full line, after activation).
Article Snippet: The DNA fragment encoding the IDR of human FUS (residues 1-215, extracted from Addgene plasmid #60362) was inserted by PCR-based cloning into the pCry2-mCh vector using Xho I- Kpn I restriction sites ( ).
