| Here , we report that , following treatment with EDTA , Puralpha was released from polyribosomes in mRNA / protein complexes ( mRNPs ) , which also contained mStaufen , Fragile 10 Mental Retardation Protein ( FMRP ) , myosin Va , and other proteins with unknown functions . ^^^ The immunoprecipitation of mStaufen and FMRP containing mRNPs provided additional evidence that the anti Puralpha detected structurally or functionally related mRNA subsets , which are distributed in the somatodendritic compartment . ^^^ |
