La red trans Golgi: clasificación en el sitio de salida del complejo Golgi
Resumen
Un nuevo modelo sugiere que la red trans Golgi clasifica las proteínas en distintas vesículas para la membrana plasmática, vesículas secretoras y lisosomas. Este último compartimento de Golgi, anteriormente conocido como GERL, es clave para el tráfico de proteínas.
Área de la Ciencia:
- Biología celular Biología celular.
- Biología Molecular Biología Molecular
- La bioquímica es la bioquímica.
Sus antecedentes:
- El complejo de Golgi procesa y empaqueta proteínas para varios destinos celulares.
- Las proteínas se mueven secuencialmente a través de los compartimentos de Golgi.
- Los lisosomas, las vesículas secretoras y las proteínas de la membrana plasmática requieren una clasificación específica.
Objetivo del estudio:
- Proponer un modelo para la clasificación de proteínas dentro del complejo de Golgi.
- Para identificar el compartimiento específico de Golgi responsable de la clasificación de distintas clases de proteínas.
- Para aclarar la función de la red trans Golgi en el tráfico de proteínas.
Principales métodos:
- El estudio se basa en un modelo propuesto, lo que implica un análisis teórico o conceptual.
- Revisión de la literatura e integración del conocimiento existente sobre la estructura y función del Golgi.
- Análisis de la localización de proteínas y vías de transporte dentro del aparato de Golgi.
Principales resultados:
- Se propone un modelo en el que la red trans Golgi clasifica las proteínas en diferentes vesículas.
- Este mecanismo de clasificación diferencia las proteínas destinadas a la membrana plasmática, las vesículas secretoras y los lisosomas.
- La red trans Golgi se identifica como el último compartimento de Golgi para este proceso de clasificación.
Conclusiones:
- La red trans Golgi juega un papel crucial en la clasificación final de las proteínas.
- Esta clasificación asegura que las proteínas lleguen a sus destinos celulares correctos.
- La red trans Golgi, anteriormente denominada GERL, se define funcionalmente por su papel en la clasificación de proteínas.

Golgi Apparatus
As they leave the Endoplasmic Reticulum (ER), properly folded and assembled proteins are selectively packaged into vesicles. These vesicles are transported by microtubule-based motor proteins and fuse together to form vesicular tubular clusters, subsequently arriving at the Golgi apparatus, a eukaryotic endomembrane organelle that often has a distinctive ribbon-like appearance.The Golgi apparatus is a major sorting and dispatch station for the products of the ER. Newly arriving vesicles enter...
Vesicular Tubular Clusters
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

Golgi Apparatus
Properly folded and assembled proteins are selectively packaged into vesicles that exit the ER. Motor proteins transport these vesicles to the Golgi apparatus for adding modifications that make these proteins functional at their destination.

Golgi Matrix Proteins
Golgi matrix proteins are a group of highly dynamic proteins that maintain the stacked structure of Golgi. These proteins adapt to rapid morphological changes of the Golgi during the cell cycle. During cell division, mild proteolysis removes these connections resulting in Golgi unstacking. In The daughter cells, these proteins help reassemble the unstacked Golgi.
One of the first identified Golgi matrix proteins was GM130, a rod-like protein located in the cis-Golgi. Subsequently, many Golgi...

Transport Across the Golgi
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
