The polar vortex (winds @ 10 hPa) is beginning to close up & detach its circulation from the high pressure system that is sliding south down the Pacific coast.

Nuclear receptor subfamily 3 group C member 1 (NR3C1:p) has 2 rigid features: a C-terminal ligand binding (in this case glucocorticoid) domain & a smaller zinc finger domain. The rest is a large dynamic/active region divvied up by a grid of PUZZLE domains (6 pS & 1 pT). #proteomics

The combination of a low pressure system centred in Michigan, a high off-shore of Maine are pumping up some wet air from the Atlantic & the Gulf of the Mad King is generating a storm in the upper Midwestern states & Southern Ontario.

Nuclear receptor interacting protein 1 (NRIP1:p) is believed to interact with the ligand binding domains of nuclear receptors, modulating their transcription factor activity. It does so without any 2°/3° structure, but uses a grid of pS PUZZLE domain controls. #proteomics

Ring finger protein 187 (RNF187:p) initiates translation at a "CGT" triplet (Leu), rather than the much more commonly used "AGT" (Met). Interestingly (for me) is the fact that the N-terminal L is co-translationally removed & N-acetyl is added to alanine exposed by that operation. #proteomics

Like NCOR1:p, nuclear receptor corepressor 2 (NCOR2:p) has ~5% of its sequence tied up in rigid structure (2× homeobox domains of unknown DNA specificity). The remaining 95% of the protein is chopped up into >10 evolutionarily conserved dynamic PUZZLE domains that do the work here. #proteomics

AT-hook containing transcription factor 1 (AH CTF1:p) has 2 interaction domains: a β-propeller & an α helix jumble, with a very narrow pS acceptor domain slotted between the two. Continuing cward, there are multiple pS acceptor PUZZLE domains located at low complexity transitions. #proteomics

Serine arginine rich matrix protein 1 (SRRM1:p) is another mRNA handling protein that eschews the cold affectation of rigid structures for the warm flexibility & comfort of dynamic ones. It also positively glimmers with gridded pS bedazzled PUZZLE domains. #proteomics

#proteomics_101 Based on the post-translational modifications listed on this diagram, provide an argument to determine which cellular compartment each of the 15 soluble regions of this ER membrane protein are exposed to in vivo (TMs in grey). How could you experimentally confirm these assignments?
