What is SMN protein used for?

The SMN complex helps to assemble the cellular machinery needed to process pre-mRNA. The SMN complex is also important for the development of specialized outgrowths from nerve cells called dendrites and axons. Dendrites and axons are required for the transmission of impulses between neurons and from neurons to muscles.

Is SMN a protein?

Survival of motor neuron or survival motor neuron (SMN) is a protein that in humans is encoded by the SMN1 and SMN2 genes. SMN is found in the cytoplasm of all animal cells and also in the nuclear gems. It functions in transcriptional regulation, telomerase regeneration and cellular trafficking.

Where is SMN protein expressed?

The SMN protein is expressed in the cytoplasm and nucleus of all eukaryotic cells, with widespread but uneven distribution in the central nervous system. Particularly high levels of protein were found to localize to the lower motor neurons of the spinal cord and brainstem.

What is a SMN?

Axonal-SMN (a-SMN), a protein isoform of the survival motor neuron gene, is specifically involved in axonogenesis.

What is the SMN complex?

SMN is part of a stable multiprotein complex that is found in all metazoan cells in the cytoplasm and in nuclear Gems. The SMN complex contains, in addition to SMN, at least six other proteins, named Gemins2–7, and plays an essential role in the assembly of the spliceosomal small nuclear ribonucleoproteins (snRNPs).

Is SMA a mutation?

SMA is caused by deletion or mutation in the SMN1 gene, which encodes a protein known as survival motor neuron (SMN). This protein plays an important role in the functioning and maintenance of motor neurons.

How can I increase my SMN protein?

Exercise can help increase levels of the survival motor neuron protein, and could potentially be used as an adjunctive therapy to treat spinal muscular atrophy (SMA), according to a recent study.

What is SMN syndrome?

Spinal muscular atrophy is a genetic disorder characterized by weakness and wasting (atrophy ) in muscles used for movement (skeletal muscles). It is caused by a loss of specialized nerve cells, called motor neurons that control muscle movement.
