Resumen
El SARS-CoV-2 utiliza modificaciones postraduccionales (PTM) para controlar las células huésped y la infección. La comprensión de estas PTM ofrece nuevas dianas terapéuticas para la COVID-19 y futuras amenazas virales.
Área de la Ciencia:
- Virología
- Biología Molecular
- Bioquímica
Sus antecedentes:
- La infección por SARS-CoV-2 implica complejas interacciones virus-huésped.
- Las modificaciones postraduccionales (PTM) son cada vez más reconocidas como reguladores clave de la patogénesis viral.
- El alcance completo de las PTM en la infección por SARS-CoV-2 aún no se comprende por completo.
Objetivo del estudio:
- Proporcionar una síntesis integral de la patogénesis del SARS-CoV-2 centrada en las PTM.
- Detallar las funciones de las PTM específicas (fosforilación, ubiquitinación, SUMOilación, etc.) en la interacción virus-huésped.
- Identificar posibles dianas terapéuticas para estrategias antivirales dirigidas al huésped.
Principales métodos:
- Síntesis y revisión de la literatura sobre PTM en la infección por SARS-CoV-2.
- Análisis de los roles mecanicistas de las PTM individuales y su diafonía.
- Exploración de herramientas computacionales para la predicción de sitios de PTM.
Principales resultados:
- Las PTM específicas como la fosforilación, la ubiquitinación y la SUMOilación modulan críticamente la función de las proteínas virales, la señalización del huésped y la evasión inmunitaria.
- Los circuitos reguladores de orden superior y la diafonía entre PTM dan forma a la dinámica de la infección.
- Los nodos enzimáticos compartidos a los que se dirigen las PTM presentan oportunidades para terapias dirigidas al huésped.
Conclusiones:
- Las PTM son reguladores centrales de la aptitud del SARS-CoV-2 y la vulnerabilidad del huésped, no solo espectadores pasivos.
- La orientación de las vías de PTM ofrece vías terapéuticas prometedoras contra el SARS-CoV-2.
- Este marco centrado en las PTM ayuda a desarrollar estrategias para pandemias virales actuales y futuras.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

02:04Covalently Linked Protein Regulators
9.8K
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

3.4K
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...

01:23Regulation of Expression at Multiple Steps
1.5K
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
