It plays a role by binding to the 7-methylguanylate cap structure at the 5’ end of mRNA facilitating ribosome assembly on mRNA. The molecular weight of eIF4E is approximately 25 kDa and it is ubiquitously expressed in various tissues across eukaryotic organisms. Additionally phosphorylation of eIF4E affects its activity and is an important post-translational modification.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nEIF4E regulates gene expression at the translational level and is a part of the eIF4F complex which also includes eIF4A and eIF4G. This complex is essential for the recruitment of ribosomes to the mRNA impacting the rate of protein synthesis. Changes in eIF4E levels can alter the translational efficiency of specific mRNAs thereby influencing cellular growth and proliferation.\u003cbr\u003e\nPathways\u003cbr\u003e\nEIF4E directly involves in the mTOR signaling pathway which regulates cell growth proliferation and survival. Within this pathway eIF4E interacts with proteins such as 4EBP1 which binds to eIF4E and inhibits its function in the absence of phosphorylation by mTOR. This interaction illustrates the control mechanism of protein synthesis under different cellular conditions connecting it to various signaling cascades.\u003cbr\u003e\nEIF4E has been linked to cancer and neurodegenerative conditions. In cancer overexpression of eIF4E leads to increased translation of oncogenes facilitating tumorigenesis. The mTOR pathway proteins like mTOR and 4EBP1 are often dysregulated in these cases. Conversely its role in neurological disorders involves the aberrant regulation of synaptic proteins like PSD95 impacting neuronal communication and function.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843803304105,"sku":"ab222974","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab222974","provider":"Iright","version":"1.0","type":"link"}
