Function

Sm-like proteins were identified in a variety of organisms based on sequence homology with the Sm protein family (see SNRPD2; MIM 601061). Sm-like proteins contain the Sm sequence motif, which consists of 2 regions separated by a linker of variable length that folds as a loop. The Sm-like proteins are thought to form a stable heteromer present in tri-snRNP particles, which are important for pre-mRNA splicing.[supplied by OMIM][7]

Interactions

LSM2 has been shown to interact with DDX20,[8] LSM3,[9][10][11][12] LSM8[9][10] and LSM7.[9][10]
