Purity ~90% (SDS-PAGE). LSM3 (u6 small nuclear RNA Associated Sm-like protein) belongs to the snRNP Sm proteins family. Sm-like proteins were identified in a variety of organisms based on sequence homology with the Sm protein family. 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. Source: Recombinant protein corresponding to aa1-102 of human LSM3, fused to His-tag at N-terminal expressed in E. coli. Molecular Weight: ~14.3kD AA
