Quantitative Proteomic Analysis Reveals JMJD6 and DNAJB11 as Endogenous Substrates of E3 Ligase RFFL The ubiquitin-proteasome system contributes to protein quality control, involving E3 ligases that ubiquitinate proteins and leading to their degradation. The dysregulation of protein degradation resul...

#GRASP55 isn't just structural—it helps lysosomal enzymes get where they’re going. New research shows that knocking out GRASP55 leads to immature β-hexosaminidase A (HEXA) being misrouted and secreted instead of reaching the lysosome. www.molbiolcell.org/doi/10.1091/... #ASCB #CellBiology #Lysosomes

Behind the scenes of cellular organization: Quantifying spatial phenotypes of puncta structures with statistical models including random fields | Molecular Biology of the Cell The cellular interior is a spatially complex environment shaped by non-trivial stochastic and biophysical processes. Within this complexity, spatial organizational principles–also called spatial pheno...

Microscopy/live imaging people! Need your help 😅

I’ve only just recently started working with large time series files (1,000+ slices) and don’t know where to start when it comes to rendering and exporting them. What software(s) do you use?

🔬 Are you eager to dive into the world of light microscopy & learn from top-notch microscopists about its essential techniques for life science applications? If that sounds exciting, don’t miss out on this free, in-depth iBiology series! 👉 www.ibiology.org/online-biolo...

Pure autofluorescence from the midband crystalline cones in a mantis shrimp eye. The fluorescence comes from mycosporine like amino acid pigments that absorb specific bands of UV light, thus tuning the UV sensitivity of the photoreceptors they focus light into. 🧪

TLR-mediated aggresome-like induced structures comprise antimicrobial peptides and attenuate intracellular bacterial survival | Molecular Biology of the Cell Immune cells employ diverse mechanisms for host defense. Macrophages, in response to TLR activation, assemble aggresome-like induced structures (ALIS). Our group has shown TLR4-signaling transcription...

Host cells take different kind of steps to fight infection. One such least understood intercellular structure is ALIS. Here Anushree et. al shows that ALIS indeed help in elimination of intracellular bacteria and also sequesters many anti-microbial peptides.

Golgi is pretty interesting organelle. Its regulation by PTM like ubiquitination is also pretty cool. Here’s the recent paper from our lab, which shows involvement of endosome associated ubiquitin E3 ligase in maintaining Golgi architecture.
