Anti-snRNP antibodies enable researchers to detect and measure the snRNP antigen in biological samples. This target is a reported synonym of the LSM2 gene, which encodes LSM2 homolog, U6 small nuclear RNA and mRNA degradation associated. This protein is known to function in RNA splicing, among other biological roles. The human version of snRNP has a canonical amino acid length of 95 residues and a protein mass of 10.8 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. snRNP is a member of the SnRNP Sm proteins protein family.
