Predicted to enable U7 snRNA binding activity and histone pre-mRNA DCP binding activity. Predicted to be involved in mRNA 3'-end processing by stem-loop binding activity and cleavage and positive regulation of G1/S transition of mitotic cell cycle. Predicted to be located in Cajal body. Predicted to be part of U7 snRNP and cytoplasmic U snRNP body. Predicted to be active in nuclear body. Orthologous to human LSM10 (LSM10, U7 small nuclear RNA associated).
