General description
A cell-permeable hydrazone compound that reversibly binds eukaryotic translation initiation factor 4E (eIF4E; KD = 25 µM) and disrupts eIF4E/eIF4G, but not eIF4E/4E-BP1, complex formation. Reported to downregulate the protein, but not mRNA, levels of c-Myc and Bcl-xL in Jurkat cells (8 h), leading to apoptotic cell death after prolonged exposure (24 h, IC50 = ~ 25 µM). Also available as a 25 mM solution in DMSO (Cat. No. 324519).

Glycosylphosphatidylinositol-specific phospholipase D1 (GPLD1) hydrolyzes inositol phosphate linkages in proteins anchored to the cell membrane. Mice overexpressing GPLD1 show enhanced neurogenesis and cognition. Snell dwarf (DW) and growth hormone receptor knockout (GKO) mice show delays in age-dependent cognitive decline. We

In ribosomopathies, perturbed expression of ribosome components leads to tissue-specific phenotypes. What accounts for such tissue-selective manifestations as a result of mutations in the ribosome, a ubiquitous cellular machine, has remained a mystery. Combining mouse genetics and in vivo ribosome profiling

Translation initiation factor 2B (eIF2B) is a master regulator of global protein synthesis in all cell types. The mild genetic Eif2b5(R132H) mutation causes a slight reduction in eIF2B enzymatic activity which leads to abnormal composition of mitochondrial electron transfer chain

Ribosomes have been suggested to directly control gene regulation, but regulatory roles for ribosomal RNA (rRNA) remain largely unexplored. Expansion segments (ESs) consist of multitudes of tentacle-like rRNA structures extending from the core ribosome in eukaryotes. ESs are remarkably variable
