Our data suggest LARP4B to act as a general stimulatory factor of translation, associated in poly(A)-mRNA-bound mRNP complexes. Under physiological conditions, LARP4B co-sedimented with polysomes in cellular extracts, suggesting a role in translation. In agreement with this notion, overexpression of LARP4B stimulated protein synthesis, whereas knockdown of the factor by RNA interference impaired translation of a large number of cellular mRNAs. |

Here we show that LARP4B is a cytoplasmic protein that co-sediments with polysomes and accumulates upon stress induction in stress granules. |

Here we show that LARP4B is a cytoplasmic protein that co-sediments with polysomes and accumulates upon stress induction in stress granules. Biochemical studies further show that the protein interacts with two key factors of the translational machinery, namely, the cytoplasmic poly(A) binding protein (PABPC1) and the receptor for activated C Kinase (RACK1). The biochemical and functional data of LARP4B presented in this study suggest a possible mode of action of LARP4B in translation. Assuming that LARP4B interacts with mRNA-associated PABPC1 and RACK1 simultaneously, it may form a bridge between the 3′ end of mRNAs and the initiating ribosome. This process would lead to mRNA circularization, possibly in an analogous way as it has been described for PABPC1 and eIF4G, the scaffold protein of the cap-binding complex. |
