LSM4 encodes the human gene, LSM4 homolog, U6 small nuclear RNA and mRNA degradation associated. It may also be known as: U6 snRNA-associated Sm-like protein LSm4; Glycine-rich protein; LSM4 homolog, U6 small nuclear RNA associated (S. cerevisiae); YER112W. The encoded protein has an amino acid length of 139 and a mass of 15.4 kDa. LSM4 is a member of the SnRNP Sm proteins family. Homologs of this gene exist in other organisms, including: Mouse, Fly, Yeast, Rat, Zebrafish, Frog, Chicken.
