Abstract A significant fraction of mRNAs is known to be associated in the form of mRNPs with microtubules for active transport. However, little is known about the interaction between mRNPs and microtubules and most of previous works were focused on molecular motor:microtubule interactions. Here, we have identified, via high resolution atomic force microscopy imaging, a significant binding of mRNA to microtubules mediated by two major mRNP proteins, YB-1 and PABP. This interaction with microtubules could be of critical importance for active mRNP traffic and for mRNP granule formation. A similar role may be fulfilled by other cationic mRNA partners.
