CC -!- FUNCTION: The SMN complex catalyzes the assembly of small nuclear
CC ribonucleoproteins (snRNPs), the building blocks of the spliceosome,
CC and thereby plays an important role in the splicing of cellular pre-
CC mRNAs (PubMed:33754639). Most spliceosomal snRNPs contain a common set
CC of Sm proteins smb1, smd1, smd2, smd3, sme1, smf1 and smg1 that
CC assemble in a heptameric protein ring on the Sm site of the small
CC nuclear RNA to form the core snRNP (By similarity). In the cytosol, the
CC Sm proteins smd1, smd2, sme1, smf1 and smg1 (5Sm) are trapped in an
CC inactive 6S pICln-Sm complex by the chaperone saf5 (By similarity). To
CC complete assembly of core snRNPs, the SMN complex accepts 5Sm from saf5
CC (By similarity). Binding of snRNA inside 5Sm ultimately triggers
CC eviction of the SMN complex, thereby allowing binding of smd3 and smb1
CC to complete assembly of the core snRNP (By similarity). Within the SMN
CC complex, yip11/gem2 constrains the conformation of 5Sm, thereby
CC promoting 5Sm binding to snRNA containing the snRNP code (a nonameric
CC Sm site and a 3'-adjacent stem-loop), thus preventing progression of
CC assembly until a cognate substrate is bound (PubMed:33754639).
CC {ECO:0000250|UniProtKB:O14893, ECO:0000269|PubMed:33754639}.
CC -!- SUBUNIT: Part of the core SMN complex at least composed of smn1,
CC yip11/gem2, gem6, gem7 and gem8 (PubMed:33754639). Interacts with smn1;
CC the interaction is direct (PubMed:26092730, PubMed:10749973,
CC PubMed:33754639). {ECO:0000269|PubMed:10749973,
CC ECO:0000269|PubMed:26092730, ECO:0000269|PubMed:33754639}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:10749973}.
CC -!- SIMILARITY: Belongs to the gemin-2 family. {ECO:0000305}.
