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.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nEIF2α acts as a regulatory component of the eIF2 complex which is central to initiating translation in eukaryotic cells. Phosphorylation of eIF2α 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 eIF2α forms part of the eIF2 complex working closely with other subunits to exert its regulatory functions.\u003cbr\u003e\nPathways\u003cbr\u003e\nEIF2α is involved in the integrated stress response (ISR) and other protein synthesis pathways. The phosphorylation state of eIF2α is important in ISR linking it to proteins such as PERK and GCN2 which respond to various stress signals. Phospho-eIF2α plays a significant role in modulating the translation response to cellular stress ensuring cells can adapt or initiate apoptosis depending on the conditions.\u003cbr\u003e\nEIF2α connects to diseases like Alzheimer's and diabetes. Alterations in phosphorylation of eIF2α are linked to endoplasmic reticulum stress in Alzheimer's affecting protein homeostasis. Connecting to diabetes dysregulated eIF2α signaling interferes with insulin synthesis and secretion. Proteins like ATF4 also intersect with eIF2α in these diseases highlighting eIF2α's involvement in critical pathological processes.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46854487146665,"sku":"ab50733","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab50733","provider":"Iright","version":"1.0","type":"link"}
