Summary: Enables chromatin binding activity and mRNA binding activity. Involved in several processes, including P-body assembly; formation of translation preinitiation complex; and post-transcriptional regulation of gene expression. Located in cytoplasmic ribonucleoprotein granule; kinetochore; and nucleus. Part of Lsm1-7-Pat1 complex and cytosolic small ribosomal subunit. Orthologous to human PATL1 (PAT1 homolog 1, processing body mRNA decay factor) and PATL2 (PAT1 homolog 2). [provided by Alliance of Genome Resources, Nov 2024]

Our results define the roles of Pat1, Lsm1, and Dhh1 in decapping of general mRNAs and suggest that these factors may monitor mRNA translation and target unique features of individual mRNAs.
Title: General decapping activators target different subsets of inefficiently translated mRNAs.
Study observations indicate that Saccharomyces cerevisiae Pat1 and Lsm1 are important for dampening ribosome transit in the 5'-UTR, and thus translation initiation of osmostress mRNAs, in particular under low stress conditions.

the studies presented here identify a set of residues at the very C-terminal end of Lsm1 to be functionally important and suggest that these residues support the function of the Lsm1-7-Pat1 complex by facilitating RNA binding either directly or indirectly
