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]
