Ho, ho, ho! Gather around, my little elves, for a tale not of the North Pole, but of the tiny, bustling workshop inside every cell of our bodies – the ubiquitin-proteasome system (UPS). This magical system, much like my own workshop, is essential for keeping things running smoothly. It’s responsible for the post-translational modification of proteins, ensuring that only the best toys—err, proteins—are kept, while the misfits are tagged for degradation.
In the vast cellular landscape, the proteasome complex is a bit like our own toy factory, ubiquitously expressed and tirelessly working to break down those not-needed or misfolded proteins, ensuring every cell remains on the ‘nice’ list. But, oh dear, over the past 14 years, it seems some of the elves in this molecular workshop have been a bit naughty, leading to a sleigh-load of human diseases linked to pathogenic variants in proteasome subunits and UPS regulators.
When the proteasome complex or its chaperons – the overseers of the assembly line – falter, it’s like a snowstorm in July; protein clearance is disrupted, and cellular homeostasis is thrown out of whack. This leads to immune dysregulation, severe inflammation, and even neurodevelopmental disorders, turning what should be a winter wonderland into a bit of a blizzard.
These proteasome-associated diseases come with a complex inheritance pattern, including monogenic, digenic, and oligogenic disorders, and can be either dominantly or recessively inherited, much like the varied patterns of snowflakes. In this review, we’ve made a list, checked it twice, and are summarizing the current known genetic causes of these proteasomal diseases. We’ll delve into the molecular pathogenesis based on the function and cellular expression of the mutated proteins in the proteasome complex, ensuring that by the end, you’ll know just how important this system is for keeping our cellular workshop merry and bright.
So, let’s jingle all the way through the complexities of the UPS and its critical role in our cellular health. After all, understanding these mechanisms is the first step in ensuring a holly, jolly cellular environment for all. Merry reading!
