About This Section

Entrez Gene summary for SMN2 Gene:
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. While
mutations in the telomeric copy are associated with spinal muscular atrophy, mutations in this gene, the
centromeric copy, do not lead to disease. This gene 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 full length 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. Four transcript variants encoding distinct isoforms have been described. (provided by RefSeq,
Sep 2008)

GeneCards Summary for SMN2 Gene: 
SMN2 (survival of motor neuron 2, centromeric) is a protein-coding gene. Diseases associated with SMN2 include adult spinal muscular atrophy, and juvenile spinal muscular atrophy. GO annotations related to this gene include protein binding and RNA binding. An important paralog of this gene is SMN1.

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

  • Spinal muscular atrophy 1 (SMA1) [MIM:253300]: A form of spinal muscular atrophy, a group of
    neuromuscular disorder 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. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Spinal muscular atrophy 2 (SMA2) [MIM:253550]: An autosomal recessive form of spinal muscular atrophy, a
    neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to
    symmetrical muscle weakness and atrophy. It has intermediate severity, with onset between 6 and 18 months.
    Patients do not reach the motor milestone of standing, and survive into adulthood. Note=The disease is caused by
    mutations affecting the gene represented in this entry
  • Spinal muscular atrophy 3 (SMA3) [MIM:253400]: An autosomal recessive form of spinal muscular atrophy, a
    neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to
    symmetrical muscle weakness and atrophy. Onset is after 18 months. Patients develop ability to stand and walk and
    survive into adulthood. Note=The disease is caused by mutations affecting the gene represented in this entry
  • Spinal muscular atrophy 4 (SMA4) [MIM:271150]: An autosomal recessive form of spinal muscular atrophy, a
    neuromuscular disorder characterized by degeneration of the anterior horn cells of the spinal cord, leading to
    symmetrical muscle weakness and atrophy. Onset is in adulthood, disease progression is slow, and patients can
    stand and walk. Note=The disease is caused by mutations affecting the gene represented in this entry
