Molecular dissection of the NH2-terminal signal/anchor sequence of rat dipeptidyl peptidase IV
Dipeptidyl peptidase IV (DPPIV) is a membrane glycoprotein with a type II orientation in the plasma membrane. As shown in a cell-free translation system, the amino-terminal 34 amino acids of rat DPPIV are involved in translocating nascent polypeptide across the membrane of microsomes and in anchoring the translocated polypeptide in the microsomal membrane. The amino-terminal sequence performing...

متن کاملA Cleavable N-Terminal Signal Peptide Promotes Widespread Olfactory Receptor Surface Expression in HEK293T Cells
Olfactory receptors (ORs) are G protein-coupled receptors that detect odorants in the olfactory epithelium, and comprise the largest gene family in the genome. Identification of OR ligands typically requires OR surface expression in heterologous cells; however, ORs rarely traffic to the cell surface when exogenously expressed. Therefore, most ORs are orphan receptors with no known ligands. To d...
متن کاملDeletion of the amino-terminal domain of asialoglycoprotein receptor H1 allows cleavage of the internal signal sequence.
Human asialoglycoprotein receptor H1 is a single-spanning membrane protein with an amino-terminal domain of 40 residues exposed to the cytoplasm and the carboxyl-terminal domain translocated to the exoplasmic side of the membrane. It has been shown earlier that the transmembrane segment functions as an internal uncleaved signal sequence for insertion into the endoplasmic reticulum. In a deletio...
متن کاملImmunocytochemical localization of the receptor for asialoglycoprotein in rat liver cells
We used high-resolution immunocytochemistry on ultrathin frozen sections labeled with colloidal gold to study the subcellular distribution of the asialoglycoprotein receptor in rat liver. The receptor was localized along the entire hepatocyte plasma membrane, including the bile capillary membrane, but was scarce intracellularly. Sinusoidal lining (Kupffer) cells and blood cells showed no immuno...
