Product details:
EIF2S1 ELISA Kit (pS51) ab282296 is a rapid single-wash 90-min Sandwich ELISA to measure EIF2S1 (pS51)in cell lysate. This SimpleStep sensitivity is 9 pg/mL.
How the assay works
EIF2S1 (pS51)SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

EIF2S1, Eukaryotic translation initiation factor 2 subunit 1, plays a key role in the initiation of protein synthesis. Dysregulation of EIF2S1 plays a part in the development of type II diabetes and ischemic injury. The immunogen from which the antibodies in this kit were raised represents the full-length mature protein. This protein shares homology across Mammalia, and therefore is expected to cross-react with many species. The protein standard in this product is recombinant human EIF2S1 ligated with peptide containing phosphorylated serine 51.

EIF2S1 also called eIF2? is a subunit of the eukaryotic translation initiation factor 2 (eIF2) complex. This protein plays an important role in the initiation of protein synthesis by regulating the binding of the initiator methionyl-tRNA to the 40S ribosomal subunit. Its molecular weight is approximately 36 kDa. EIF2S1 is widely expressed in various tissues providing a fundamental function in protein biosynthesis across different cell types.
Biological function summary
EIF2? acts as a regulatory component of the eIF2 complex which is central to initiating translation in eukaryotic cells. Phosphorylation of eIF2? leads to inhibition of the exchange of GDP to GTP on eIF2 effectively reducing global protein synthesis while allowing the translation of specific mRNAs involved in stress responses. The eIF2? forms part of the eIF2 complex working closely with other subunits to exert its regulatory functions.
Pathways
EIF2? is involved in the integrated stress response (ISR) and other protein synthesis pathways. The phosphorylation state of eIF2? is important in ISR linking it to proteins such as PERK and GCN2 which respond to various stress signals. Phospho-eIF2? plays a significant role in modulating the translation response to cellular stress ensuring cells can adapt or initiate apoptosis depending on the conditions.
EIF2? connects to diseases like Alzheimer's and diabetes. Alterations in phosphorylation of eIF2? are linked to endoplasmic reticulum stress in Alzheimer's affecting protein homeostasis. Connecting to diabetes dysregulated eIF2? signaling interferes with insulin synthesis and secretion. Proteins like ATF4 also intersect with eIF2? in these diseases highlighting eIF2?'s involvement in critical pathological processes.
