General annotation (Comments)

Function	The SMN complex plays an essential role in spliceosomal snRNP assembly in the cytoplasm and is required for pre-mRNA splicing in the nucleus.
Subunit structure	Part of the core SMN complex that contains SMN1, SIP1/GEMIN2, DDX20/GEMIN3, GEMIN4, GEMIN5, GEMIN6, GEMIN7, GEMIN8 and STRAP/UNRIP. Interacts directly with GEMIN3 and with several snRNP SM core proteins, including SNRPB, SNRPD1, SNRPD2, SNRPD3 and SNRPE. Interacts with PPP4R2.
Subcellular location	Cytoplasm. Nucleus. Nucleus › nucleolus. Note= Localized in subnuclear structures next to coiled bodies, called gems, which are highly enriched in spliceosomal snRNPs and in the nucleolus.
