The Sm antigen is part of the spliceosomal complex catalyzing the splicing of nuclear pre-mRNA. Each spliceosome snRNP consists of snRNAs (U1, U2, U4/U6, and U5) bound to a unique set of proteins as well as a shared set of seven different Sm proteins with molecular weights between 9 and 29.5 kDa (typically SmB/SmB', SmD1, SmD2, SmD3, SmE, SmF, SmG). Most frequently the SmB and SmD polypeptides are targets of the anti-Sm specific autoimmune response, of which SmD is regarded the most SLE-specific Sm antigen.
