How to Learn SUMOylation: From SAE1–UBA2 and UBC9 to SUMO Chains, SENP Editing, Stress Responses and Genome Control
Quick Read. SUMOylation is a reversible post-translational modification in which Small Ubiquitin-like Modifier proteins are covalently attached to lysines on target proteins. The core human pathway uses the SAE1–UBA2 E1 activating enzyme, the UBC9/UBE2I E2 conjugating enzyme, E3 ligases that sharpen substrate selection, and SENP proteases that mature SUMO precursors and remove SUMO from substrates.…

How to Learn ER-Phagy: From FAM134B and TEX264 to ER Fragmentation, Autophagosome Capture, Lysosomal Turnover and Proteostasis
Quick Read. ER-phagy is selective autophagic turnover of the endoplasmic reticulum. Cells use receptor proteins such as FAM134B, RTN3L, CCPG1, SEC62, ATL3 and TEX264 to identify ER regions for capture by autophagic membranes and delivery to lysosomes. The process helps control ER size, remove damaged or protein-loaded ER subdomains, and restore proteostasis after stress. One-sentence…

How to Learn Protein Tyrosine Sulfation: From PAPS and SLC35B2 to TPST1/TPST2, Golgi Modification and Extracellular Recognition
Quick Read. Protein tyrosine sulfation is a post-translational modification that adds sulfate to selected tyrosine residues of secreted and membrane proteins as they pass through the trans-Golgi network. The sulfate donor is PAPS, the Golgi transporter SLC35B2 supplies luminal PAPS, and the enzymes TPST1 and TPST2 install the modification. Sulfotyrosine can strengthen extracellular protein–protein recognition…
