The smn complex: an assembly machine for rnps
WebSpinal muscular atrophy is caused by deletions or mutations in the SMN1 gene that result in reduced expression of the SMN protein. The SMN protein is an essential molecular chaperone that is required for the biogenesis of multiple ribonucleoprotein (RNP) complexes including spliceosomal small nuclear RNPs (snRNPs). WebSMN is part of a multiprotein complex The SMN protein is a 294-amino-acid polypeptide that oligomerizes and forms a complex with at least five additional proteins: Gemin2 (formerly known as SIP1), Gemin3/dp103 (a DEAD-box RNA helicase), Gemin4, Gemin5 (a WD-repeat protein) and Gemin6 [22–27].
