Abstract Background Messenger RNA mRNA comprises three major parts a 5 -UTR UnTranslated Region a coding region and a 3 -UTR. The 3 -UTR contains signal sequences involved in polyadenylation degradation and localization stabilization processes. Some sequences in the 3 -UTR are involved in the localization of mRNAs in . neurons epithelial cells oocytes and early embryos but such localization has been most thoroughly studied in neurons. Neuronal polarity is maintained by the microtubules MTs found along both dendrites and axon and is partially influenced by sub-cellular mRNA localization. A widely studied mRNA is that for Tau protein which is located in the axon hillock and growth cone its localization depends on the well-characterized cis-acting signal U-rich region in the 3 -UTR. Methods We compared the cis-acting signal of Tau with mRNAs in the axonal regions
