Function
Function in SwissProt
Activator of decapping that functions as a general and active mechanism of translational repression and required for P-body formation. First decay factor recruited to mRNA, at a time when the mRNA is still associated with translation factors. Subsequently, PAT1 recruits the hepta-heterodimer LSM1-LSM7 complex to P-bodies. In association with the LSM1-LSM7 complex, stabilizes the 3' terminus of mRNAs. This association is also required for mosaic virus genomic RNA translation. Modulates the rates of mRNA-decapping that occur following deadenylation. Might be required for promoting the formation or the stabilization of the preinitiation translation complexes. Required for 40S ribosomal subunit joining to capped and/or polyadenylated mRNA. With other P-body components, enhances the formation of retrotransposition-competent Ty1 virus-like particles. Necessary for accurate chromosome transmission during cell division.
