MAG (myelin associated glycoprotein) or SIGLEC4A is a single-pass type I transmembrane protein belonging to the sialic acid binding Ig-like lectin (SIGLEC) family in the immunoglobulin superfamily (IgSF). SIGLECs are characterized by an N-terminal Ig-like V-type (IgV)domain that mediates sialic acid binding, followed by varying numbers (2 to 17) of Ig-like C2-type (IgC2) domains in the extracellular region, a transmembrane region, and a cytoplasmic tail with intracellular immunoreceptor tyrosine-based inhibitory motifs (ITIM). They can be classified into two subgroups: Siglecs-1, -2, and -4 subgroup, and a Siglec-3/CD33-related subgroup (Siglecs-3, and -5 through -13), defined by sequence similarity and clustered gene localization. MAG contains 4 IgC2 domains and binds to sialylated gangliosides to mediate certain myelin-neuron cell-cell interactions.  MAG peferentially binds to alpha-2,3-linked sialic acid and ganglioside Gt1b.  MAG protects motoneurons against apoptosis, also after injury; protection against apoptosis is probably mediated via interaction with neuronal RTN4R and RTN4RL2. MAG inhibits axon outgrowth by binding to RTN4R.  MAG is required to prevent degeneration of myelinated axons in adults; this probably depends on binding to gangliosides on the axon cell membrane.  Mutations affecting the MAG gene are associated with Spastic paraplegia 75 (SPG75),  an autosomal recessive, neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs..

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
