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

Notes
Human SMN/Gemin 1 SimpleStep ELISA® kit is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of SMN/Gemin 1 protein in Cell Lysate. Quantitate Human SMN/Gemin 1 with 18.2 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

- Activity summary
SMN also known as Survival of Motor Neuron protein or Gemin 1 is an important protein involved in the assembly of small nuclear ribonucleoproteins (snRNPs). It has a molecular mass of approximately 38 kDa. SMN proteins are expressed in almost all tissues with highest levels in spinal cord and brain tissues. They play a mechanical role in Gemin complex assisting RNA processing tasks which are essential in RNA metabolism alongside other Gemin proteins.
- Biological function summary
The SMN protein operates within the SMN-Gemin complex a multi-protein assembly important for snRNP biogenesis and pre-mRNA splicing. This complex coordinates the maturation and transport of snRNPs facilitating the processing of precursor mRNAs in the nucleus. SMN and associated Gemin proteins mediate the assembly of Sm proteins onto snRNA ensuring accurate splicing mechanisms necessary for gene expression.
- Pathways
The SMN protein is notably involved in the chaperone-assisted assembly pathway related to snRNP biogenesis. It plays a central role in the spliceosome assembly process working closely with Sm proteins and other RNA-binding proteins. Importantly SMN interacts with the ribonucleoprotein complex influencing mRNA splicing which integrates into the broader cell signaling pathways such as the cholinergic agonist pathways and RNA splicing pathways that regulate neuromuscular communication.
- Associated diseases and disorders
The deficiency or malfunction of SMN protein directly relates to Spinal Muscular Atrophy (SMA) an autosomal recessive disorder. SMA is characterized by motor neuron degeneration which can be attributed to insufficient SMN protein levels leading to compromised snRNP assembly and splicing. The SMN1 gene deletion or mutation reduces the available SMN protein linking this defect with the severity of SMA. Studies suggest that altering the expression levels of the related SMN2 gene can potentially modulate disease outcomes further emphasizing the connection between SMN protein and SMA pathogenesis.
