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:9845364, PubMed:18984161). Most spliceosomal snRNPs
CC contain a common set of Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3,
CC SNRPE, SNRPF and SNRPG that assemble in a heptameric protein ring on
CC the Sm site of the small nuclear RNA to form the core snRNP (Sm core)
CC (PubMed:18984161). In the cytosol, the Sm proteins SNRPD1, SNRPD2,
CC SNRPE, SNRPF and SNRPG are trapped in an inactive 6S pICln-Sm complex
CC by the chaperone CLNS1A that controls the assembly of the core snRNP
CC (PubMed:18984161). To assemble core snRNPs, the SMN complex accepts the
CC trapped 5Sm proteins from CLNS1A forming an intermediate
CC (PubMed:18984161). Within the SMN complex, SMN1 acts as a structural
CC backbone and together with GEMIN2 it gathers the Sm complex subunits
CC (PubMed:21816274, PubMed:22101937, PubMed:17178713). Binding of snRNA
CC inside 5Sm ultimately triggers eviction of the SMN complex, thereby
CC allowing binding of SNRPD3 and SNRPB to complete assembly of the core
CC snRNP (PubMed:31799625). Ensures the correct splicing of U12 intron-
CC containing genes that may be important for normal motor and
CC proprioceptive neurons development (PubMed:23063131). Also required for
CC resolving RNA-DNA hybrids created by RNA polymerase II, that form R-
CC loop in transcription terminal regions, an important step in proper
CC transcription termination (PubMed:26700805). May also play a role in
CC the metabolism of small nucleolar ribonucleoprotein (snoRNPs).

CC -!- DISEASE: Spinal muscular atrophy 1 (SMA1) [MIM:253300]: A form of
CC spinal muscular atrophy, a group of neuromuscular disorder
CC characterized by degeneration of the anterior horn cells of the spinal
CC cord, leading to symmetrical muscle weakness and atrophy. Autosomal
CC recessive forms are classified according to the age of onset, the
CC maximum muscular activity achieved, and survivorship. The severity of
CC the disease is mainly determined by the copy number of SMN2, a copy
CC gene which predominantly produces exon 7-skipped transcripts and only
CC low amount of full-length transcripts that encode for a protein
CC identical to SMN1. Only about 4% of SMA patients bear one SMN1 copy
CC with an intragenic mutation. SMA1 is a severe form, with onset before 6
CC months of age. SMA1 patients never achieve the ability to sit.

CC -!- MISCELLANEOUS: The SMN gene is present in two highly homologous and
CC functional copies (TelSMN/SMN1 and CenSMN/SMN2). The telomeric copy of
CC SMN gene (TelSMN/SMN1) seems to be the SMA-determining gene while the
CC centromeric copy seems unaffected.
CC -!- MISCELLANEOUS: [Isoform SMN]: Primarily derived from SMN1 gene.
CC -!- MISCELLANEOUS: [Isoform SMN-delta7]: Thought to be a non-functional
CC protein that lacks the capacity to oligomerize and thus cannot interact
CC with Sm proteins. Primarily derived from SMN2 gene.
CC {ECO:0000305|PubMed:10500148}.
CC -!- SIMILARITY: Belongs to the SMN family. {ECO:0000305}.
