Anti-LSM4 antibodies are used in the immunodetection of the protein LSM4 homolog, U6 small nuclear RNA and mRNA degradation associated. In humans, the canonical protein has a reported length of 139 amino acid residues and a mass of 15.4 kDa. Its subcellular localization is in the nucleus. A member of the SnRNP Sm proteins protein family, LSM4 is known to play a role in pre-mRNA splicing as component of the U4/U6-U5 tri-snRNP complex that is involved in spliceosome assembly, and as component of the precatalytic spliceosome (spliceosome B complex). Synonyms for this target antigen include YER112W, U6 snRNA-associated Sm-like protein LSm4, LSM4 U6 small nuclear RNA and mRNA degradation associated, LSM4 homolog, U6 small nuclear RNA associated, glycine-rich protein, and GRP. LSM4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of LSM4 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
