ProteomicsThiocarboxylation of Urm1 is regulated by tightly-controlled biochemical checkpoints
Ubiquitin related modifier 1 (Urm1) is a highly conserved member of the Ubiquitin-like (UBL) family of proteins. Urm1 is a key component of the eukaryotic thiolation cascade, which is responsible for introducing sulfur at U34 in several eukaryotic tRNAs. Like other UBLs, Urm1 is also able to conjuga...

ProteomicsE2/E3-independent ubiquitin-like protein conjugation by Urm1 is directly coupled to cysteine persulfidation
Posttranslational modifications by ubiquitin-like proteins (UBL) are essential for nearly all cellular processes. Ubiquitin related modifier 1 (Urm1) is a non-canonical UBL which plays a key role in tRNA anticodon thiolation as a sulfur carrier protein (SCP). While Urm1 has also been observed to con...

ProteomicsCryo-EM structures of the human Elongator complex at work
The deposited data concern the mapping of acetylation sites on wild-type and the K280A, Y363A mutants of Elp3 by LC-MS/MS. Abstract of the manuscript: tRNA modifications affect ribosomal elongation speed and co-translational folding dynamics. The Elongator complex is responsible for introducing 5-ca...

ProteomicsAutophosphorylation of conserved yeast and human casein kinase 1 isozymes regulates Elongator dependent tRNA modifications
Casein kinase 1 (CK1) family members are crucial for ER-Golgi trafficking, calcium signaling, DNA repair, tRNA modifications and circadian rhythmicity. Whether and how substrate interactions and kinase autophosphorylation contribute to these diverse cellular processes and CK1 plasticity remains larg...
