LSM4, also called u6 snRNA-associated Sm-like protein or glycine-rich protein (GRP), forms donut-shaped heptameric complexes that are involved in various steps of RNA metabolism. It facilitates RNA protein interactions and structural changes that are required during ribosomal subunit assembly. It binds specifically to the 3-terminal u-tract of u6 snRNA. Source: Recombinant protein corresponding to aa1-139 of human LSM4, fused to His-tag at N-terminal expressed in E. coli.
