Multiplexing of TMT labeling reveals folate-deficient diet-specific proteome changes in NTDs

Frontiers in Cell and Developmental Biology
Introduction: In the early stage of embryonic development, the neural tube (NT) cannot be closed properly due to some complex factors, including environmental factors, genetic factors, and the relationship between various factors, leading to the ...

Protein synthesis rates and ribosome occupancies reveal determinants of translation elongation rates

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Although sequencing of ribosome footprints has uncovered aspects of mRNA translation, the determinants of ribosome flux remain incompletely understood.

Change in Nutritional Status Modulates the Abundance of Critical Pre-initiation Intermediate Complexes During Translation Initiation \u3cem\u3ein Vivo\u3c/em\u3e [PDF]

, 2007
In eukaryotic translation initiation, eIF2∙GTP–Met-tRNAiMet ternary complex (TC) interacts with eIF3–eIF1–eIF5 complex to form the multifactor complex (MFC), while eIF2∙GDP associates with eIF2B for guanine nucleotide exchange.

Single‐Cell Transcriptomics Unravels Growth Factor Erv1‐Like Mediated Ferroptosis as a Key Driver of Intestinal Epithelial Dysfunction in Ulcerative Colitis

Advanced Science, EarlyView.
Single‐cell transcriptomic profiling of ulcerative colitis (UC) tissues identified downregulation of GFER in intestinal epithelial cells. Mechanistically, GFER interacts with PCBP1 to help maintain intracellular iron homeostasis and may also reduce lipid peroxidation by activating the PGC‐1α/PPARγ signaling pathway, thereby inhibiting ferroptosis ...

Schlafen14 Impairs HIV-1 Expression in a Codon Usage-Dependent Manner

Viruses
Schlafen (SLFN) is a family of proteins upregulated by type I interferons with a regulatory role in translation. Intriguingly, SLFN14 associates with the ribosome and can degrade rRNA, tRNA, and mRNA in vitro, but a role in translation is still unknown ...

Anticodon Engineered Transfer RNA (tRNASUAG) Inhibits Hepatitis B Virus Replication by Promoting the Degradation of Core Protein

Advanced Science, EarlyView.
This study employed tRNASUAG, an anticodon‐engineered tRNA (ACE‐tRNA), to introduce a phosphorylatable serine into the C‐terminal domain of HBc by reading through its stop codon, thereby potentially promoting the ubiquitin‐proteasome degradation of HBc, and subsequently inhibiting HBV replication. Through a tRNASUAG‐gHBV1‐tRNASUAG‐gHBV2‐tRNASUAG tandem

Structural and Functional Versatility of the Amyloidogenic Non‐Amidated Variant of the Antimicrobial Peptide Citropin 1.3

Advanced Science, EarlyView.
Citropin 1.3 is an antimicrobial peptide derived from amphibians that forms amyloid structures. Here, the structural and functional properties of citropin 1.3 are characterized. Using high‐resolution imaging approaches, a variety of canonical and undescribed fibril morphologies are identified.

Ubiquitination of stalled ribosome triggers ribosome-associated quality control

Nature Communications, 2017
Translation arrest by polybasic sequences induces ribosome stalling, and the arrest product is degraded by the ribosome-mediated quality control (RQC) system. Here we report that ubiquitination of the 40S ribosomal protein uS10 by the E3 ubiquitin ligase

Hypoxia‐Induced circPRELID2 Promotes Gastric Cancer Metastasis by Facilitating ZEB2 Translation via PCBP1 O‐GlcNAcylation

Advanced Science, EarlyView.
Under hypoxia, HIF1A is directly bound to the PRELID2 promoter to increase PRELID2 pre‐mRNA expression, followed by the DYRK1A–SFPQ–SAM68 complex binding to Alu‐containing introns in PRELID2 pre‐mRNA, leading to circPRELID2 circularization. CircPRELID2 interacts with PCBP1 and promotes its cytoplasmic retention.
