Myo2p is an essential class V myosin in budding yeast with several identified functions in organelle trafficking and spindle orientation. The present study demonstrates that Myo2p is a component of a large RNA-containing complex (Myo2p-RNP) that is distinct from polysomes based on sedimentation analysis and lack of ribosomal subunits in the Myo2p-RNP. Microarray analysis of RNAs that coimmunoprecipitate with Myo2p revealed the presence of a large number of mRNAs in this complex. The Myo2p-RNA complex is in part composed of the RNA processing body (P-body) based on coprecipitation with P-body protein subunits and partial colocalization of Myo2p with P-bodies. P-body disassembly is delayed in the motor mutant, myo2-66, indicating that Myo2p may facilitate the release of mRNAs from the P-body.
