Dick G, Akslen-Hoel L, Grondahl F, Kjos I, Maccarana M, Prydz K
Glycobiology
. 2014 Aug;
25(1):30-41.
PMID: 25138304
Proteoglycan (PG) sulfation depends on activated nucleotide sulfate, 3'-phosphoadenosine-5'-phosphosulfate (PAPS). Transporters in the Golgi membrane translocate PAPS from the cytoplasm into the organelle lumen where PG sulfation occurs. Silencing of...

. 2013 Jun;
61(8):606-16.
PMID: 23757342
Heparan sulfate proteoglycans are hypothesized to contribute to the filtration barrier in kidney glomeruli and the glycocalyx of endothelial cells. To investigate potential changes in proteoglycans in diabetic kidney, we...

J Histochem Cytochem
. 2012 Sep;
60(12):926-35.
PMID: 22941419
A large number of complex glycosylation mechanisms take place in the Golgi apparatus. In epithelial cells, glycosylated protein molecules are transported to both the apical and the basolateral surface domains....

. 2010 Dec;
346(1):50-7.
PMID: 21126737
The sulphation patterns of glycosaminoglycan (GAG) chains are decisive for the biological activity of their proteoglycan (PG) templates for sugar chain polymerization and sulphation. The amounts and positions of sulphate...

Am J Physiol Regul Integr Comp Physiol
. 2009 Apr;
297(1):R26-33.
PMID: 19339678
Patients with congestive heart failure (CHF) experience increased skeletal muscle fatigue. The mechanism underlying this phenomenon is unknown, but a deranged extracellular matrix (ECM) might be a contributing factor. Hence,...

418(3):517-28.
PMID: 19076065
PGs (proteoglycans) are proteins acquiring long, linear and sulfated GAG (glycosaminoglycan) chains during Golgi passage. In MDCK cells (Madin-Darby canine kidney cells), most of the CS (chondroitin sulfate) PGs are...

PMID: 17965432
The canine 3'-phosphoadenosine 5'-phosphosulfate (PAPS) transporter 1 fused to GFP was stably expressed with a typical Golgi localization in MDCK II cells (MDCK II-PAPST1). The capacity for PAPS uptake into...
