Resumen
Dos modelos explican cómo las proteínas se ensamblan en las membranas celulares. La hipótesis de la señal y el plegamiento desencadenado por la membrana ofrecen marcos para comprender la biogénesis de las proteínas y la inserción de la membrana.
Área de la Ciencia:
- Biología Molecular Biología Molecular
- La bioquímica es la bioquímica.
- Biología celular Biología celular.
Sus antecedentes:
- El ensamblaje de proteínas en membranas biológicas es crucial para la función celular.
- Se han propuesto dos hipótesis primarias, la hipótesis de la señal y el plegamiento desencadenado por la membrana, para explicar este proceso.
Objetivo del estudio:
- Revisar y sintetizar datos recientes sobre la biogénesis de proteínas de membrana.
- Para comparar y contrastar la hipótesis de la señal y los modelos plegables desencadenados por membrana.
Principales métodos:
- Revisión de la literatura de estudios recientes sobre la inserción y el plegamiento de proteínas de membrana.
- Análisis comparativo de los datos experimentales que apoyan cada hipótesis.
Principales resultados:
- La hipótesis de la señal postula que las proteínas específicas guían las cadenas de polipéptidos hacia la membrana durante la síntesis.
- La hipótesis del plegamiento desencadenado por la membrana sugiere un autoensamblaje impulsado por cambios conformacionales al entrar en la membrana.
Conclusiones:
- Ambas hipótesis proporcionan marcos valiosos para la comprensión de la biogénesis de las proteínas de membrana.
- Datos recientes ofrecen información sobre los mecanismos de inserción y plegamiento de proteínas dentro de las membranas biológicas.

What are Membranes?
A key characteristic of life is the ability to separate the external environment from the internal space. To do this, cells have evolved semi-permeable membranes that regulate the passage of biological molecules. Additionally, the cell membrane defines a cell’s shape and interactions with the external environment. Eukaryotic cell membranes also serve to compartmentalize the internal space into organelles, including the endomembrane structures of the nucleus, endoplasmic reticulum and Golgi...
What are Membranes?
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries markers that...
Membrane Lipids
Lipids are an essential component of all biological membranes. The average lipid content in mammalian membranes is 50%, though it can be as low as 20% in the inner mitochondrial membrane or as high as 80% in the myelin sheath present around the nerve cells.
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

Membrane Proteins
Plasma membranes have integral transmembrane proteins involved in facilitated transport. These proteins are collectively referred to as transport proteins, and they function as either channels for the material or as carriers themselves. Channel proteins have hydrophilic domains exposed to the intracellular and extracellular fluids and a hydrophilic channel through their core that provides a hydrated opening for solutes to pass through the membrane layers. Passage through the channel allows...
Assembly of the Lipid Bilayer in the ER
Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...
