Blood feeding arthropods produce anti-inflammatory salivary proteins called evasins that function through inhibition of chemokine-receptor signalling in the host. Herein, we show that the evasin ACA-01 from the Amblyomma cajennense tick can be post-translationally sulfated at two tyrosine residues, ...

Embryonic stem (ES) cells continuously decide whether to maintain pluripotency or differentiate. While exogenous LIF and BMP4 perpetuate a pluripotent state, less is known about factors initiating differentiation. We show that heparan sulfate (HS) proteoglycans are critical co-receptors for signals ...

Tyrosine sulfation is a common posttranslational modification in mammals. To date, it has been thought to be limited to secreted and transmembrane proteins, but little is known about tyrosine sulfation on nuclear proteins.To search for tyrosine sulfation on nuclear proteins, we purified the nucleus ...

Tyrosine sulfation is an understudied posttranslational modification (PTM) of crucial biological significance. Conventional liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods are unable to directly identify sulfation sites due to the high lability of the sulfate PTM. In this study, we...

Inhibition of the SLC35B2-TPST2 axis of tyrosine sulfation attenuates the growth and metastasis of pancreatic ductal adenocarcinoma
Protein sulfation can be crucial in regulating protein-protein interactions but remains largely underexplored. Sulfation is near-isobaric to phosphorylation, making it particularly challenging to investigate using mass spectrometry. The degree to which tyrosine sulfation (sY) is misidentified as pho...

Protein tyrosine sulfation (sY) is a post-translational modification (PTM) catalysed by Golgi-resident Tyrosyl Protein Sul-foTransferases (TPSTs). Information on protein tyrosine sulfation is currently limited to ~50 human proteins with only a handful of those having verified sites of sulfation. The...

Background & Aims: Pancreatic ductal adenocarcinoma (PDAC) is the fourth leading cause of cancer deaths in the United States. Tyrosine sulfation, catalyzed by the tyrosylprotein sulfotransferase 2 (TPST2), is a post-translational modification essential for protein-protein interactions and cellular f...
