LSM5 encodes the human gene, LSM5 homolog, U6 small nuclear RNA and mRNA degradation associated. It may also be known as: U6 snRNA-associated Sm-like protein LSm5; LSM5 homolog, U6 small nuclear RNA associated (S. cerevisiae); YER146W. The encoded protein has an amino acid length of 91 and a mass of 9.9 kDa. Other isoforms may exist. LSM5 is a member of the SnRNP Sm proteins family. Homologs of this gene exist in other organisms, including: Mouse.
