LSM1
Introduction
U6 snRNA-associated Sm-like protein LSm1 is a protein that in humans is encoded by the LSM1 gene.[1][2][3]
Function
Function
Sm-like proteins were identified in a variety of organisms based on sequence homology with the Sm protein family (see SNRPD2). 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.[3]
