It is a 31-kilodalton protein that binds to the poly(A) tail of pre-mRNA and stimulates the assembly of the polyadenylation complex thereby influencing the maturation and stability of mRNA transcripts. This protein is predominantly expressed in the nucleus of eukaryotic cells where it performs its important function in post-transcriptional regulation.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPABPN1 is involved in controlling the polyadenylation process of pre-mRNA which is essential for producing mature mRNA molecules. PABPN1 operates within a multi-protein complex that includes enzymes like poly(A) polymerase and cleavage stimulation factor (CstF). By interacting with these proteins PABPN1 ensures the correct formation of the 3' end of mRNA influencing gene expression regulation and mRNA stability.\u003cbr\u003e\nPathways\u003cbr\u003e\nPABPN1 participates in key cellular pathways such as mRNA processing and nuclear export of mRNA. It operates in concert with other proteins like PABPC1 which aids in the transition of mRNA from the nucleus to the cytoplasm. The protein maintains the balance of mRNA stability and translation efficiency which are critical aspects of efficient gene expression.\u003cbr\u003e\nPABPN1 mutations are linked to oculopharyngeal muscular dystrophy (OPMD) a genetic condition that leads to muscle weakness. Another related disorder involves its interaction with proteins like HSP70 where its dysfunction may contribute to disrupted protein homeostasis in affected tissues. Studying PABPN1's role in these diseases provides insight into the molecular mechanisms underlying these conditions and aids in the development of potential therapeutic strategies.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46848644972713,"sku":"ab264328","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab264328","provider":"Iright","version":"1.0","type":"link"}
