<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

Component of LSm protein complexes, which are involved in RNA processing and may function in a chaperone-like manner, facilitating the efficient association of RNA processing factors with their substrates. Component of the cytoplasmic LSM1-LSM7 complex, which is involved in mRNA degradation by activating the decapping step in the 5'-to-3' mRNA decay pathway. In association with PAT1, LSM1-LSM7 binds directly to RNAs near the 3'-end and prefers oligoadenylated RNAs over polyadenylated RNAs. Component of the nuclear LSM2-LSM8 complex, which is involved in splicing of nuclear mRNAs. LSM2-LSM8 associates with multiple snRNP complexes containing the U6 snRNA (U4/U6 di-snRNP, spliceosomal U4/U6.U5 tri-snRNP, and free U6 snRNP). It binds directly to the 3'-terminal U-tract of U6 snRNA and plays a role in the biogenesis and stability of the U6 snRNP and U4/U6 snRNP complexes. LSM2-LSM8 probably also is involved degradation of nuclear pre-mRNA by targeting them for decapping, and in processing of pre-tRNAs, pre-rRNAs and U3 snoRNA. Component of a nucleolar LSM2-LSM7 complex, which associates with the precursor of the RNA component of RNase P (pre-P RNA) and with the small nucleolar RNA (snoRNA) snR5. It may play a role in the maturation of a subset of nucleolus-associated small RNAs.6 Publications

Component of the heptameric LSM1-LSM7 complex that forms a seven-membered ring structure with a doughnut 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. LSM1-LSM7 associates also with PAT1 and XRN1. Component of the heptameric LSM2-LSM8 complex that forms a seven-membered ring structure with a doughnut shape; an RNA strand can pass through the hole in the center of the ring structure. The LSm subunits are arranged in the order LSM8, LSM2, LSM3, LSM6, LSM5, LSM7 and LSM4. LSM2-LSM8 associates with PAT1 and XRN1. Component of a LSM2-LSM7 complex, which consists of at least LSM2, LSM3, LSM4, LSM5, LSM6 and LSM7.
