Fig. 5. Distinct domains of Mal3 mediate comet formation and LLPS.
a, Condensates formed by full-length Mal3 and Mal3 truncations (1 µM) in the presence of 5% PEG-35k. b, Unlabelled FLMal3 (200 nM, scaffold) tagged with FL-Mal3:mCherry (2 nM, tag) was allowed to recruit Mal3:GFP (2 nM, client) in the presence of PEG-6k. Graphs show distributions of tag and scaffold Mal3 intensities (arrow denotes the threshold applied for speckle detection in images). c, Intensity of Mal3:GFP (full-length or truncated constructs) recruited to FL-Mal3 scaffold droplets. Lines show median, and numbers in the shaded area (N) show number of droplets analysed (one experiment per construct). d,e, Kymographs showing end-tracking by Mal3/Tip1/Tea2 in the presence of full-length Mal3 (d) or Mal3-ΔIDR2 (e) and in the absence of PEG. f,g, Intensities of Mal3-Alexa647 (f) and Tip1:GFP (g) in the comets forming in the presence of FL-Mal3 or Mal3-ΔIDR2. Lines show median, and numbers in the shaded area (N) show number of comets analysed (pooled across two independent experiments per condition). Numerical data are available in source data.
