Resumen

La red cis-Golgi (CGN) es un compartimento ampliamente conservado en células animales, vegetales y de levadura, que desempeña un papel clave en el transporte de proteínas. Este resumen aclara su presencia y características fundamentales en eucariotas.

Área de la Ciencia:

Biología Celular
Biología Molecular
Estructura Celular Eucariota

Sus antecedentes:

El aparato de Golgi exhibe polaridad cis-a-trans, con la red cis-Golgi (CGN) y la red trans-Golgi (TGN) regulando la entrada y salida de proteínas de carga.
La presencia generalizada de la red cis-Golgi (CGN) en diversos eucariotas ha sido objeto de investigación y debate continuos.

Objetivo del estudio:

Consolidar los hallazgos recientes que apoyan la conservación de la red cis-Golgi (CGN) en células animales, vegetales y de levadura.
Proponer una terminología consistente para la red cis-Golgi (CGN) para abordar la confusión existente.
Destacar las características fundamentales de la red cis-Golgi (CGN) a pesar de las variaciones morfológicas.

Principales métodos:

Revisión y síntesis de la literatura científica reciente sobre la estructura y función del aparato de Golgi.
Análisis comparativo de datos morfológicos y estudios funcionales en diferentes especies de eucariotas.
Clarificación de la terminología relacionada con los compartimentos de la red de Golgi.

Principales resultados:

La evidencia apoya la red cis-Golgi (CGN) como un compartimento comúnmente conservado en células animales, vegetales y de levadura.
A pesar de las significativas variaciones específicas de la especie en la morfología del Golgi y la CGN y su relación con los sitios de salida del retículo endoplásmico (ERES), existen puntos en común fundamentales.
Tanto la CGN como la TGN funcionan como compartimentos de clasificación móviles que pueden operar independientemente del cuerpo principal de Golgi.

Conclusiones:

La red cis-Golgi (CGN) es un orgánulo fundamental y ampliamente conservado en eucariotas.
Se propone el uso consistente del término CGN para mejorar la claridad en la comunicación científica.
La CGN y la TGN son estaciones de clasificación dinámicas cruciales para el tráfico de proteínas, incluso cuando están separadas de la pila principal de Golgi.

Golgi Apparatus

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.

Golgi Apparatus

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.
The Golgi apparatus is a eukaryotic organelle that has a distinctive ribbon-like appearance. It is a primary sorting and dispatch station for cargo arriving from the ER. Newly arriving vesicles enter the cis face of the Golgi, closest to the ER, and are...

Transport Across the 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...

Golgi Matrix Proteins

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...

Coat Assembly and GTPases

Coat Assembly and GTPases

Vesicles incorporate different coat protein subunits in different cell locations, which changes the properties of the coat, such as the shape and geometry of the transport vesicles. Thus, vesicle coat proteins also play a significant role in cargo selection.
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...

Vesicular Tubular Clusters

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.
With the help of motor proteins such...
