    Summary
    Enables protein kinase binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to act upstream of or within mRNA catabolic process and spliceosomal tri-snRNP complex assembly. Predicted to be located in cytoplasm and nucleoplasm. Predicted to be part of Lsm1-7-Pat1 complex; Lsm2-8 complex; and nucleus. Predicted to be active in P-body. Orthologous to human LSM2 (LSM2 homolog, U6 small nuclear RNA and mRNA degradation associated). [provided by Alliance of Genome Resources, Apr 2022]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
