RC TISSUE=Testis; RA Ansorge W., Wirkner U., Mewes H.-W., Gassenhuber J., Wiemann S.; RL Submitted (DEC-1999) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: The SMN complex plays an essential role in spliceosomal CC snRNP assembly in the cytoplasm and is required for pre-mRNA CC splicing in the nucleus. It may also play a role in the metabolism CC of snoRNPs. CC -!- SUBUNIT: Part of the core SMN complex that contains SMN1, SIP1, CC GEMIN2, GEMIN3, GEMIN4, GEMIN5, GEMIN6 and GEMIN7. Interacts CC directly with SMN1 and with several spliceosomal snRNP core Sm CC proteins, including SNRPB, SNRPD2 and SNRPD3. Interacts with EBV CC EBNA2 and EBNA3C. CC -!- SUBCELLULAR LOCATION: Cytoplasmic and nuclear. Localized in CC subnuclear structures next to coiled bodies, called Gemini of CC Cajal bodies (Gems). CC -!- TISSUE SPECIFICITY: Ubiquitous. CC -!- SIMILARITY: Belongs to the DEAD box helicase family.
