About This Section

Entrez Gene summary for SMN1:
This gene is part of a 500 kb inverted duplication on chromosome 5q13. This duplicated region contains at least four
genes and repetitive elements which make it prone to rearrangements and deletions. The repetitiveness and complexity
of the sequence have also caused difficulty in determining the organization of this genomic region. The telomeric and
centromeric copies of this gene are nearly identical and encode the same protein. However, mutations in this gene, the
telomeric copy, are associated with spinal muscular atrophy; mutations in the centromeric copy do not lead to disease.
The centromeric copy may be a modifier of disease caused by mutation in the telomeric copy. The critical sequence
difference between the two genes is a single nucleotide in exon 7, which is thought to be an exon splice enhancer.
Note that the nine exons of both the telomeric and centromeric copies are designated historically as exon 1, 2a, 2b,
and 3-8. It is thought that gene conversion events may involve the two genes, leading to varying copy numbers of each
gene. The protein encoded by this gene localizes to both the cytoplasm and the nucleus. Within the nucleus, the
protein localizes to subnuclear bodies called gems which are found near coiled bodies containing high concentrations
of small ribonucleoproteins (snRNPs). This protein forms heteromeric complexes with proteins such as SIP1 and GEMIN4,
and also interacts with several proteins known to be involved in the biogenesis of snRNPs, such as hnRNP U protein and
the small nucleolar RNA binding protein. Two transcript variants encoding distinct isoforms have been described.
(provided by RefSeq, Sep 2008)

UniProtKB/Swiss-Prot: SMN_HUMAN, Q16637
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. It may also play a role in the metabolism of snoRNPs

About This Section

UniProtKB/Swiss-Prot: SMN_HUMAN, Q16637 (See protein sequence)
Recommended Name: Survival motor neuron protein  
Size: 294 amino acids; 31849 Da
Subunit: Component of an import snRNP complex composed of KPNB1, RNUT1, SMN1 and ZNF259. Part of the core SMN complex
that contains SMN1, GEMIN2/SIP1, DDX20/GEMIN3, GEMIN4, GEMIN5, GEMIN6, GEMIN7, GEMIN8 and STRAP/UNRIP. Interacts with
DDX20, FBL, NOLA1, RNUT1, SYNCRIP and with several spliceosomal snRNP core Sm proteins, including SNRPB, SNRPD1,
SNRPD2, SNRPD3, SNRPE and ILF3. Interacts with OSTF1, LSM10 and LSM11
Subcellular location: Cytoplasm. Nucleus, gem. Note=Localized in subnuclear structures next to coiled bodies, called
Gemini of Cajal bodies (Gems)
Miscellaneous: The SMN gene is present in two highly homologous and functional copies (TelSMN/SMN1 and CenSMN/SMN2).
The telomeric copy of SMN gene (TelSMN/SMN1) seems to be the SMA-determining gene while the centromeric copy seems
unaffected

  • Defects in SMN1 are the cause of spinal muscular atrophy autosomal recessive type 1 (SMA1) [MIM:253300].
  • Spinal muscular atrophy refers to a group of neuromuscular disorders characterized by degeneration of the anterior
    horn cells of the spinal cord, leading to symmetrical muscle weakness and atrophy. Autosomal recessive forms are
    classified according to the age of onset, the maximum muscular activity achieved, and survivorship. The severity of
    the disease is mainly determined by the copy number of SMN2, a copy gene which predominantly produces exon 7-skipped
    transcripts and only low amount of full-length transcripts that encode for a protein identical to SMN1. Only about 4%
    of SMA patients bear one SMN1 copy with an intragenic mutation. SMA1 is a severe form, with onset before 6 months of
    age. SMA1 patients never achieve the ability to sit
  • Defects in SMN1 are the cause of spinal muscular atrophy autosomal recessive type 2 (SMA2) [MIM:253550]. SMA2
  • is an autosomal recessive spinal muscular atrophy of intermediate severity, with onset between 6 and 18 months.
    Patients do not reach the motor milestone of standing, and survive into adulthood
  • Defects in SMN1 are the cause of spinal muscular atrophy autosomal recessive type 3 (SMA3) [MIM:253400]. SMA3
  • is an autosomal recessive spinal muscular atrophy with onset after 18 months. SMA3 patients develop ability to stand
    and walk and survive into adulthood
  • Defects in SMN1 are the cause of spinal muscular atrophy autosomal recessive type 4 (SMA4) [MIM:271150]. SMA4
  • is an autosomal recessive spinal muscular atrophy characterized by symmetric proximal muscle weakness with onset in
    adulthood and slow disease progression. SMA4 patients can stand and walk
