== Function ==
[https://www.uniprot.org/uniprot/PAT1_YEAST PAT1_YEAST] 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.<ref>PMID:8816497</ref> <ref>PMID:8972867</ref> <ref>PMID:10523645</ref> <ref>PMID:10394921</ref> <ref>PMID:10747033</ref> <ref>PMID:10779343</ref> <ref>PMID:10913177</ref> <ref>PMID:11027264</ref> <ref>PMID:10761922</ref> <ref>PMID:11514438</ref> <ref>PMID:12773554</ref> <ref>PMID:16179257</ref> <ref>PMID:17875743</ref> <ref>PMID:17429074</ref> <ref>PMID:17513695</ref> <ref>PMID:18086885</ref> <ref>PMID:19901074</ref> <ref>PMID:20832728</ref>
