14 / Silencing this gene
From Mag to a sequence that silences it
The AUMsilence™ platform designs the sequences against the mouse transcripts on this page. Six decisions are yours before it does. What is written under each is AUM's guidance; the timings and the concentrations are in the usage guide below.
01
Choose the region
A knockdown oligonucleotide can sit in the 5' untranslated region, the coding sequence or the 3' untranslated region, and all three are used. The coding sequence and the 3' untranslated region are the usual first choices for an RNase H design; the 5' end near the start codon suits a steric block. The map above shows where each region sits on the isoforms it draws.
02
Cover the isoforms you mean
An exon every isoform carries silences the whole gene; an exon only some isoforms carry silences those and spares the rest. Decide which you want before a sequence is chosen, and check the reference transcript (MANE Select in human; RefSeq Select and Ensembl canonical in mouse and rat) is the one your cells express.
03
Think across species early
The orthologs panel says whether mouse and rat carry the same gene. Whether one oligonucleotide can serve two species is a sequence question, settled at design by matching the candidate against each transcript, not by the protein identity shown there.
04
Check expression in your model
A transcript that is not expressed in your cells cannot show knockdown. Confirm the gene is expressed in the cell type and condition you will use, from your own data or a reference atlas, before the order. The expression panel above gives GTEx's median per tissue for a human gene; for mouse and rat it says that no atlas is on this page yet.
The median is the middle sample of a tissue, so a gene expressed in a few cells of a mixed tissue reads low here and may still be the one your cell type needs. Nothing on this panel is adjusted or averaged across tissues; each figure is the source's own, and a tissue GTEx did not sample is absent from the chart.

Run the controls
A scramble control of the same chemistry, a positive control against a gene known to knock down in your cells, untreated cells, and a mock condition where a transfection reagent is used. Read knockdown at the RNA level first, then at the protein; the usage guide gives the timing and the concentrations to start from.
06
Pick the product
AUMsilence sdASO needs no transfection reagent and works in the cells that resist one. AUMsilence toASO is the transfection-optimised version of the same design, and AUMsiRNA™ is the siRNA route. The selection guide compares them.
77,295 PubMed-indexed papers mention Mag at Europe PMC, newest first. Europe PMC ignores letter case, so the count also covers the human symbol where it differs from this one only in case.

Gene summary
This gene encodes a type I membrane protein and member of the immunoglobulin-like superfamily. It is expressed in myelinating glial cells, including oligodendrocytes of the central nervous system and Schwann cells of the peripheral nervous system. Mice lacking the encoded protein express abundant myelin, but suffer long-term axon degeneration, altered distribution of channels and adhesion molecules at nodes of Ranvier, and altered axon cytoskeletal structure. While not required for myelination, the encoded protein enhances axon-myelin stability, helps to structure nodes of Ranvier, and regulates the axon cytoskeleton. Alternative splicing results in multiple transcript variants.

Adhesion molecule that mediates interactions between myelinating cells and neurons by binding to neuronal sialic acid-containing gangliosides and to the glycoproteins RTN4R and RTN4RL2 (PubMed:12089450, PubMed:27922006, PubMed:7533044). Not required for initial myelination, but seems to play a role in the maintenance of normal axon myelination (PubMed:10625334, PubMed:7516497, PubMed:9262180, PubMed:9469574, PubMed:9482781, PubMed:9482783). Protects motoneurons against apoptosis, also after injury; protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2 (PubMed:26335717). Required to prevent degeneration of myelinated axons in adults; this probably depends on binding to gangliosides on the axon cell membrane (PubMed:15953602, PubMed:19158290). Negative regulator of neurite outgrowth that inhibits axon longitudinal growth (PubMed:12089450, PubMed:19158290, PubMed:27922006). Negative regulator of neurite outgrowth; in dorsal root ganglion neurons the inhibition is mediated primarily via binding to neuronal RTN4R or RTN4RL2 and to a lesser degree via binding to neuronal gangliosides (PubMed:17640868). In cerebellar granule cells the inhibition is mediated via binding to neuronal gangliosides (PubMed:17640868). In sensory neurons, inhibition of neurite extension depends only partially on RTN4R, RTN4RL2 and gangliosides (By similarity). Inhibits axon outgrowth by binding to RTN4R (PubMed:12089450). Preferentially binds to alpha-2,3-linked sialic acid (PubMed:27922006, PubMed:7533044). Binds ganglioside Gt1b (PubMed:27922006)

One pixel of the map above stands for several bases, and a block too short to see is drawn wider than its own scale, so the map chooses a region and the sequence here chooses the window. Click an exon on a row of the map, or drag across a row; then set the exact start and end below.

No transcript is chosen.
Once a window is chosen this panel shows its length, its G and C count as a percentage of that length, the letters it is made of, the exons it falls in, whether it crosses a junction, and its antisense strand.

Drawn 5' to 3' from each transcript's exons as placed on the reference assembly; exon 1 is the 5' exon on the transcript's own strand. Exon blocks are to scale with each other; introns are drawn at one fixed width whatever their length, so the map is not to scale along the chromosome. Numbers are exon ranks along the strand; a rank is omitted where the exon is too narrow to carry it.
