Eukaryotic Initiation Factor (eIF)
Eukaryotic initiation factors (eIFs) are proteins involved in the initiation phase of eukaryotic translation. These proteins help stabilize the formation of the functional ribosome around the start codon and also provide regulatory mechanisms in translation initiation.
Eukaryotic initiation factor 2B (eIF2B) is a guanine nucleotide-exchange factor which mediates the exchange of GDP (bound to initiation factor eIF2) for GTP, thus regenerating the active [eIF2.GTP] complex that is required for peptide-chain initiation. The activity of eIF2B is a key control point for eukaryotic protein synthesis and is altered in response to viral infection, hormones, nutrients, growth factors and certain stresses.
Eukaryotic translation initiation factor 4E (eIF4E) is best known for its function in the initiation of protein synthesis on capped mRNAs in the cytoplasm. Eukaryotic initiation factor (elF) 4A functions as a subunit of the initiation factor complex elF4F, which mediates the binding of mRNA to the ribosome.

NVS1.1
0 ImagesCat. No.: HY-177569NVS1.1 is an orally active, blood-brain barrier-penetrant eRF1 degrader. NVS1.1 induces ubiquitination of eRF1 at Lys279, mediates proteasomal degradation via the E3 ubiquitin ligases RNF14 and RNF25 as well as the translational stress sensor GCN1, traps eRF1 at the ribosomal A-site, inhibits translation termination and triggers ribosome collision. As a readthrough enhancer, NVS1.1 enables near-cognate tRNA incorporation at premature termination codons by reducing intracellular eRF1 levels. NVS1.1 activates ribosome-associated quality control pathways via ribosome collision, including ubiquitination of small subunit ribosomal proteins. NVS1.1 restores functional full-length CFTR and IDUA proteins and reduces glycosaminoglycan accumulation in relevant models. NVS1.1 can be used in the research of cystic fibrosis and Hurler syndrome (mucopolysaccharidosis type I, MPS I).
