Protein

Sm-like protein LSm1

Gene

LSM1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Component of the cytoplasmic LSM1-LSM7 complex which is involved in mRNA degradation by activating the decapping step. The LSM1-LSM7 complex binds RNA with a preference for poly-U ends.4 Publications

Interactioni

Subunit structurei

Component of the heptameric LSM1-LSM7 complex that forms a seven-membered ring structure with a donut shape. The LSm subunits are arranged in the order LSM1, LSM2, LSM3, LSM6, LSM5, LSM7 and LSM4. Except for LSM1, where a C-terminal helix crosses the ring structure to form additional interactions with LSM3 and LSM6, each subunit interacts only with its two neighboring subunits. The LSM1-LSM7 complex interacts with PAT1; within the complex PAT1 has direct interactions with LSM2 and LSM3.5 Publications
