Gene Information

human ... SMN1(6606)

General description

Survival motor neuron 1 (SMN1), also known as gemin 1, is a survival motor neuron protein, which is highly expressed in spinal cord. SMN1 is localized on the telomeric region of human chromosome 5q13. The 38kDA protein is expressed mostly in nucleus and cytoplasm.

Immunogen

Purified recombinant fragment of human SMN1 expressed in E.coli.
Mouse monoclonal antibody raised against SMN1

Biochem/physiol Actions

Survival motor neuron 1 (SMN1) is involved in the synthesis of full length survival motor neuron (SMN) mRNA transcripts. SMN1 also contributes to the biogenesis and assembly of snRNP (small nuclear riboproteins) in the cytoplasm, which plays an important role in pre-mRNA splicing or processing. Axonal SMN protein mediates the growth of axon and mRNA axonal transport. Mutations in the SMN1 gene has been associated with a genetic neurodegenerative disease called spinal muscular atrophy(SMA).

Physical form

Ascitic fluid containing 0.03% sodium azide.
