Phosphorylation of P-stalk proteins defines the ribosomal state for interaction with auxiliary protein factors

EMBO Reports
Ribosomal action is facilitated by the orchestrated work of trans-acting factors and ribosomal elements, which are subject to regulatory events, often involving phosphorylation.

Ribosomal trafficking is reduced in Schwann cells following induction of myelination

Frontiers in Cellular Neuroscience, 2015
Local synthesis of proteins within the Schwann cell periphery is extremely important for efficient process extension and myelination, when cells undergo dramatic changes in polarity and geometry.

Fine‐Tuned Regulation of mRNA Translation and Transport by STAU2 Condensate Facilitates Neuronal Development and Plasticity

Advanced Science, EarlyView.
STAU2 undergoes phase separation to form dynamic condensates that package target mRNAs and deliver them to the distal ends of growing neuronal dendrites. STAU2 condensates stabilize embedded mRNAs and repress their translation. Synaptic activity bidirectionally remodels STAU2 condensates, coordinating local translation of STAU2‐associated mRNAs ...

Effect of growth medium composition on the efficiency of non-ribosomal synthesis in bacteria of the genus Bacillus [PDF]

BIO Web of Conferences
Bacteria of the genus Bacillus are known for their ability to suppress a wide range of pathogenic microflora through the production of a variety of secondary metabolites, a significant proportion of which are non-ribosomal peptides.

Targeting PLD3 Reverses the Immunosuppressive Niche by Reprogramming Tumor‐Associated Macrophages and Potentiates Antitumor Immunity

Advanced Science, EarlyView.
PLD3 activates the lysosomal‐AKT‐NF‐κB axis to drive cellular senescence in macrophages, establishing an immunosuppressive TME by limiting the infiltration of cytotoxic T, NK, and NKT cells, which confers resistance to anti‐PD‐1 therapy. Abrine inhibits PLD3 expression, restoring antitumor immunity and synergizing with anti‐PD‐1 treatment.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

Advanced Science, EarlyView.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

Anti-ribosomal P2: could it be a useful new criterion for patients with systemic lupus erythematosus?

Egyptian Rheumatology and Rehabilitation
Background Systemic lupus erythematosus is a multisystem autoimmune disorder that displays numerous autoantibodies such as anti-nuclear, anti-Smith, anti-double-stranded DNA, and anti-ribosomal antibodies.

Nutrient availability dictates the regulation of metabolism by the ribosomal protein-MDM2-p53 pathway

Molecular & Cellular Oncology, 2018
Nutrient availability alters ribosomal biogenesis, causing ribosomal proteins to act as secondary messengers of nutrient response by binding to MDM2 and activating p53. Recent work suggests that the ribosomal protein (RP)-MDM2-p53 pathway responds to the

Conformational switches control early maturation of the eukaryotic small ribosomal subunit

eLife, 2019
Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, EarlyView.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...
