SNRPE, also known as SME, aids in the cytoplasmic construction of the usnRNPs by binding to a conserved Sm site on usnRNA and forming a stable snRNP core complex. As a core protein to usnRNP, the SNRPE associates with the entire u family of snRNAs including u1-u6. SNRPE also interacts with DDX20 and Small nuclear ribonucleoprotein polypeptide F. Source: Recombinant protein corresponding to aa1-92 of human SNRPE, fused to His-tag at N-terminal expressed in E. coli.
