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.

    L-Azetidine-2-carboxylic acid (Standard)
    		Activator
    L-Azetidine-2-carboxylic acid is a proline analog. L-Azetidine-2-carboxylic acid upregulates the lipid autophagy marker LC3-II via activation of the PERK pathway. L-Azetidine-2-carboxylic acid increases pro-apoptotic BAX protein. L-Azetidine-2-carboxylic acid induces ATF6 cleavage and upregulates phosphorylated eIF2α levels. L-Azetidine-2-carboxylic acid induces ER stress, inducing protein misfolding and aggregation. L-Azetidine-2-carboxylic acid shows teratogenic, pro-inflammatory and pro-apoptotic effects.

  • HY-138844
    3-AP-Me
    3-AP-Me is a dimethyl derivative of the nucleotide reductase inhibitor 3-AP (SML0568). 3-AP-Me can activate the endoplasmic reticulum (ER) stress pathway by promoting the phosphorylation of eIF2α and increasing the gene expression of transcription factors ATF4 and ATF6, leading to cell apoptosis. Additionally, 3-AP-Me can activate the stress kinases c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinases. 3-AP-Me also leads to the upregulation of the spliced mRNA variant XBP1, can be used in cancer research.

    1,2,4-Trihydroxybenzene (Standard)
    		Activator
    1,2,4-Trihydroxybenzene (Hydroxyhydroquinone) (Standard) is the analytical standard of 1,2,4-Trihydroxybenzene (HY-W010451). This product is intended for research and analytical applications. 1,2,4-Trihydroxybenzene (Hydroxyhydroquinone) is an ER stress inducer that targets proteins such as PKR-like ER kinase PERK to induce cytotoxicity. 1,2,4-Trihydroxybenzene selectively activates eIF2α phosphorylation, activates the PERK-eIF2α signaling pathway and induces stress granule formation. 1,2,4-Trihydroxybenzene subsequently exacerbates oxidative stress and causes DNA double-strand breaks, destroying organelles such as mitochondria and ER, and inducing cell death. 1,2,4-Trihydroxybenzene also has the potential to exhibit anti-tumor effect, increase blood pressure, and relieve spasm.
