RA Colinge J., Superti-Furga G., Bennett K.L.; RL Submitted (OCT-2008) to UniProtKB. 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, CC SIP1/GEMIN2, DDX20/GEMIN3, GEMIN4, GEMIN5, GEMIN6, GEMIN7, GEMIN8 CC and STRAP/UNRIP. Interacts directly with SMN1 and with several CC spliceosomal snRNP core Sm proteins, including SNUPN, SNRPB, CC SNRPD2 and SNRPD3. Interacts with PPP4R2. Interacts with EBV EBNA2 CC and EBNA3C.
