It is a small protein with a molecular weight of approximately 14 kDa. 4E-BP2 is expressed in various tissues with a prominent presence in the brain. This protein binds to eukaryotic initiation factor 4E (eIF4E) inhibiting the initiation of cap-dependent translation by preventing eIF4E from assembling into the larger eIF4F complex.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nThe 4E-BP2 protein inhibits the initiation of protein synthesis regulating gene expression at a translational level. 4E-BP2 does not form part of a stable complex but transiently interacts with eIF4E in response to different cellular signals. When 4E-BP2 is phosphorylated by mammalian target of rapamycin (mTOR) it undergoes a conformational change that weakens its binding to eIF4E allowing protein synthesis to proceed. This regulation exhibits tissue specificity and involves responses to growth factors nutrients and cellular stress.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe involvement of 4E-BP2 is important in the mTOR signaling pathway a central pathway regulating cell growth and metabolism in response to environmental cues. The mTOR pathway includes other proteins like eIF4E which 4E-BP2 interacts with directly and mTOR itself which phosphorylates 4E-BP2. Additionally 4E-BP2 also participates in the insulin signaling pathway influencing how cells respond to insulin and other growth factors by regulating protein translation.\u003cbr\u003e\nAltered 4E-BP2 function has implications in neurological disorders and cancer. In the brain dysregulation of 4E-BP2 is associated with autism spectrum disorders as its role in neural development and plasticity is important. In cancer aberrant activity of 4E-BP2 can lead to unchecked cellular proliferation due to disrupted control of protein synthesis. The protein's regulation by mTOR links it to various cancers as increased mTOR activity can result in decreased 4E-BP2 activity facilitating tumorigenesis.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46854350766249,"sku":"ab111309","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab111309","provider":"Iright","version":"1.0","type":"link"}
