Shumpei Maruyama @shumpeim.bsky.social · 02/07/2026We realized that the lysosome is actually a decent place to be if you're an algae trying to photosynthesize. The acidic properties of the lysosome and its bicarbonate transporters can work together to concentrate inorganic carbon for photosynthesis. You just need to resist digestion. (5/7) 110 0
Shumpei Maruyama @shumpeim.bsky.social · 02/07/2026It had long been hypothesized that the symbiosome forms by preventing fusion with lysosomes, but we found the exact opposite. Instead we found that symbiosis relies on the proper function of lysosomal proteins, such as SLC26A11, and that the symbiosome recruits several digestive enzymes. (4/7) 100 0
Shumpei Maruyama @shumpeim.bsky.social · 02/07/2026Through careful proteomics, microscopy, RNAi, and CRISPR/Cas9-mutagenesis experiments, we identified that the symbiont-housing organelle forms through fusion with lysosomes - where things are usually digested.
