N-glycosylation requirements for the AT1a angiotensin II receptor delivery to the plasma membrane.
The purpose of this work was to investigate the role of N-glycosylation in the expression and pharmacological properties of the the rat AT1a angiotensin II (AII) receptor. Glycosylation-site suppression was carried out by site-directed mutagenesis (Asn-->Gln) of Asn176 and Asn188 (located on the second extracellular loop) and by the removal of Asn4 at the N-terminal end combined with the replac...
متن کاملN-linked glycosylation is required for optimal proteolytic activation of membrane-bound transcription factor CREB-H.
CREB-H is a liver-enriched bZIP transcription factor of the CREB3 subfamily. CREB-H is activated by intramembrane proteolysis that removes a C-terminal transmembrane domain. Aberrant expression of CREB-H is implicated in liver cancer. In this study we characterized N-linked glycosylation of CREB-H in the luminal domain at the C-terminus. We found that CREB-H is modified at three N-linked glycos...
متن کاملDe novo ceramide synthesis is required for N-linked glycosylation in plasma cells.
Plasma cells (PCs) are terminally differentiated B lymphocytes responsible for the synthesis and secretion of Igs. The differentiation of B cells into PCs involves a remarkable expansion of both lipid and protein components of the endoplasmic reticulum. Despite their importance in many signal transduction pathways, the role of ceramides, and of complex sphingolipids that are derived from cerami...
متن کاملAT1a receptor signaling is required for basal and water deprivation-induced urine concentration in AT1a receptor-deficient mice.
It is well recognized that ANG II interacts with arginine vasopressin (AVP) to regulate water reabsorption and urine concentration in the kidney. The present study used ANG II type 1a (AT(1a)) receptor-deficient (Agtr1a(-/-)) mice to test the hypothesis that AT(1a) receptor signaling is required for basal and water deprivation-induced urine concentration in the renal medulla. Eight groups of wi...
متن کاملN-linked protein glycosylation is required for full competence in Campylobacter jejuni 81-176.
The recent sequencing of the virulence plasmid of Campylobacter jejuni 81-176 revealed the presence of genes homologous to type IV secretion systems (TFSS) that have subsequently been found in Helicobacter pylori and Wolinella succinogenes. Mutational analyses of some of these genes have implicated their involvement in intestinal epithelial cell invasion and natural competence. In this report, ...
