Those Pesky Post Translational Modifications (opens in new tab)

I’ve written here many times about various post-translational protein modifications. That’s a huge field of study, because it has become more and more clear over the years that it’s not so much that living cells have huge numbers of different protein sequences in them (although they have plenty!) it’s that every protein seems to be modifiable by a long list of add-ons. These include (but are absolutely guaranteed not to be limited to!) phosphorylation, ubiquitination, farnesylation, glycosyla...
