Presence of terminal N-acetylgalactosamine residues in subregions of the endoplasmic reticulum is influenced by cell differentiation in culture
(The American Society for Biochemistry and Molecular Biology, 1991)
Using Helix pomatia lectin as a specific probe for terminal, nonreducing N-acetylgalactosamine residues, glycoprotein precursors bearing newly initiated O-linked oligosaccharides have been localized in the lumen of the ...

Trimeric G proteins modulate the dynamic interaction of PKAII with the Golgi complex
(The Company of Biologists Ltd, 1999)
The Golgi complex represents a major subcellular location of protein kinase A (PKA) concentration in mammalian cells where it has been previously shown to be involved in vesicle-mediated protein transport processes. We ...

Protein kinase A activity is required for the budding of constitutive transport vesicles from the trans-Golgi network
(National Academy of Sciences of the USA, 1997)
We have examined the role played by protein kinase A (PKA) in vesicle-mediated protein transport from the trans-Golgi network (TGN) to the cell surface. In vivo this transport step was inhibited by inhibitors of PKA catalytic ...

Regulación de la estructura y función del complejo de Golgi por factores citosólicos y proteínas G heterotriméricas
(1996)
Las células eucariotas están organizadas en una serie de compartimentos delimitados por membranas lipídicas. En cada comportamiento se realizan actividades características, que son la expresión funcional de las moléculas ...

Trimeric G proteins regulate the cytosol-induced redistribution of Golgi enzymes into the endoplasmic reticulum
(Company of Biologists Ltd, 1995)
Streptolysin O-permeabilized cells incubated with a high concentration (5-10 mg/ml) of cytosolic proteins and ATPgenerating system exhibit redistribution into the endoplasmic reticulum (ER) of Golgi integral proteins ...

Caracterización de un subcompartimento proteolítico en el retículo endoplásmico de condrocitos
(1996)
LOS CONDROCITOS DE POLLO EN CULTIVO SINTETIZAN EL PROTEOGLICANO AGRECAN COMO UN PRECURSOR DE 370 KDA QUE ES GLICOSILADO Y SECRETADO AL MEDIO DE CULTIVO CON UNA VIDA MEDIA DE 30 MINUTOS. HEMOS DEMOSTRADO CON ESTUDIOS ...

A Regulatory Role for cAMP-dependent Protein Kinase in Protein Traffic along the Exocytic Route
(The American Society for Biochemistry and Molecular Biology, 1996)
The influence of protein kinase A activity on transport of newly synthesized vesicular stomatitis virus G glycoprotein along the exocytic pathway was examined. Transport of vesicular stomatitis virus G glycoprotein ...
